Gilson liquid handler, please HELP! [30 Aug 2011|11:20am]

jformaldehydem
Heya guys, hope people are still listening out there...

We've recently acquired a Gilson GX-271 autosampler liquid handler that we're using as an autosampler. The methods we have set up for it are very basic and a pain in the arse but I am aware that we are not properly utilising the software.

To cut the question short, I am fairly proficient at programming and I'd like to learn the syntax for programming the methods (ie: If/EndIf, Goto, DoOnlyIn). Gilson, being the business geniuses (ie: greedy imperialistic fucks) that they are have decided in their wisdom that they are not going to put anything about operators, variables or expressions in their manual, but rather invite you to their advanced training seminar, which is great if you happen to be fortunate enough to live in a country where Gilson has a presence, which I do not and our agents' knowledge of the advanced features of the sampler leaves a bit to be desired.

So what I want to know is, does anybody out there have experience with the advanced programming features of Trilution, and if so could you PLEASE help me out with some basic syntax parameters.

Many thanks in advance.

Chemical VC startups [16 Apr 2008|02:22pm]

I read this article the other day, and it got me thinking.
Does anyone on this board run or have had experience with a start-up venture capitalist company (chemical or instrumental company)? How did you go about starting it and why did you get into it? Also, if you started the company or one of the major projects while in graduate school, how did your school help (or not) you out?

I have a really stupid question here about FTIR. Does anyone know of a way to determine the anharmonicity constant (X_e) without using the actual vibrational frequency?

Hi Guys,

Since this post will get to a large amount on institutes and universities, I thought I would see if I can use the union that has been created here to see if anyone knows of any jobs available for me.

I am an Electron Microscopist (mainly TEM and SEM) so if you know of anyone in your department that has TEMs, looking for analysis of nanomaterial or has a lot of money as I am not cheap (kidding about this one), then please place a comment.

I suppose this could have gone into chemistry help but I thought since this is a livejournal network of mainly working chemists in academia I though i would abuse this system.

Any offers get a nice atomic hug!

Hello everybody!
I'm new around here, both this community and LJ as well, and I thought I'd say I exist :)
I'm in my second year of study in Industrial Chemistry at the University of Padua, Italy. I don't have pretty much any experience apart from the courses labs, but I already like them more than straight classroom lessons. I feel I can understand more if I'm actually DOING what I'm taught about.
I don't know yet what to specialise in, but that will come with time, I guess.

And that's basically it.
BE seeing you in the future.

So, I'm sitting here at like 2:30 am. Reflecting on the fact i've given myself like a day to study all of my instrumental notes for my final exam on Tuesday. I have like an encyclopedia of notes to look over. I need to know the ins and outs and the finer points of the instruments we learned about(Spectrophotometers, IR Devices, Mass spectroscopy, Electrophoresis, every kind of chromatography you can think of). At least the mantra of instrumental seems easy enough to remember "If it doesn't work make a derivative that does what you want it to." :P I found the lab more fun than the class itself. So I've spent most of the time before now preparing my lab notebook to reflect my love of the labs. Probably spending more time than I should be on it. :P I keep telling myself after the final I'll never have to remember such a large amount of information again ,but then I remember I signed up for the second half of the course. D:

It isn't that bad though. The class has satisfied my curiosity of how the instruments I've been using work. It may be a lot to remember, but it's really neat and I'm glad I took the course(well I WAS required to). It's just so much to remember, with no real set patterns between them. I don't think I can remember them in the detail my professor wants for the exam. I'm sure I'll do fine though. I can't wait for the second half of the course.

:D

I'm desperately in need of someone being able to give me a decent example and explanation regarding how to solve the pH levels of acids and bases.

Much appreciated :)

I just felt like visiting, since I haven't been here in so long. Among other things, this year I'm going to be taking physics 11, principles math 12, a college-level biology course and chemistry 12, so I'm going to be SWAMPED! I'll make sure to ask you any intriguing chemistry questions I happen upon in the course of my studies.

The other day I happened upon a mention of alkanes, alkenes & alkynes, and I was very excited to find them again. So I looked in my textbook (my previous school closed, so I got to keep a chem textbook and a bio textbook) and discovered that... they are really complicated! You forget very easily when you haven't taken it for a while. I hope I come across them again this year.

Nerd transmission over. =P

Hey,

I was wondering if it's normal to have no idea what you want to go to grad school for(with a chemistry BS)? :P

I really have no clue what I'd like to do ,but I know I want to go to grad school. I really enjoy the subject material and my professors are pushing me to go. I'm doing research with my professor over the summer right now with P-chem and it doesn't really seem to be my thing. I sit at a computer all day writing code. I prefer to be up and running around doing things. Even though I don't like it I'm probably going to be doing my senior thesis(i'll be a senior in the fall) on it. It'll probably be much easier that way. I enjoyed Inorganic and Organic chemistry. My inorganic professor suggested I go for organometallo chemistry or something ,since it's a combination of the two. Haven't had analytical yet ,but I did have a pseudo-one and it seemed alright.

I guess what I'm looking for are ideas I guess? Or is it just you go to graduate school for inorganic/organic chemistry and that's that or what? What should I look for in a grad school?

This is all so overwhelming or maybe I'm just making it out to be that way. D:

thanks for any help/advice/whatever.

organic help... [24 Jun 2007|04:48pm]

hey guys :)

i'm collecting alcohol emissions in water and sorbent tubes and would like to analyze them using HPLC. i'm having a hard time finding a method for derivatization of alcohols using benzoyl chloride. i know that the reaction needs to take place in an alkaline solution and that's about it.

anyways, has anyone done this? if so, do you have a procedure? if you haven't done this and have any input it would be greatly appreciated.

Tygone tubing [11 Jun 2007|12:07pm]

I'm doing some HPLC work and I was wondering if anyone knows whether or not acetonitrile will degrade Tygone (sometimes spelled tygon) tubes? I know that certain organics, especially the pure organics can eat up tygone, but I cannot find anything on how acetonitrile affects tygone. Any info would be appreciated.

Does anyone who frequents this blog know of a good introductory geochemistry textbook? Something that would be associated with a senior undergraduate or masters course.

Hi! For my inorganic lab I have to synthesize an octahedral first row transistion metal complex(and perform other things on it) and I was wondering if any of you had neat/cool suggestions for such a compound.

Thanks!

May be cross-posted later...(most likely to the chemistry help community)

Question to people who have done internships(at universitys/colleges) [01 Feb 2007|01:45pm]

[ mood | busy ]

So, I was thinking about doing a summer internship or something to that effect. What I was wondering were how these things are? I'm more or less worried about whether or not I'd be able to do anything. I'm a junior chemistry major. At the close of this semster I will have done nearly everything I need to do to graduate(the only course i'd need to take would be Instrumental Methods of Anaylsis and the senior thesis ,but that doesn't count). Even with this though I'm worried I wouldn't do very well at an internship. I do want to do an internship thingy though. I'd just hate to jump into something and have no idea what to do. I guess what I want to know is how these things usually are? :/

I discovered this community while on a search for someplace I can talk about chemistry and not bore people to death! I'm Ally, I'm 16 and in Chemistry 11. Not close to being a major I suppose, but I do enjoy chemistry a lot and tend to bore people with it. I actually heard about Mole Day and informed my teacher... although unfortunately it was too late to celebrate it. My pet subject at the moment is alkenes and alkynes... we're learning about them right now and they're quite fascinating.

Am I the only person who always laughs when she sees "INADEQUATE" as a NMR technique discussed in a paper?

I mean, I know it's legit... but I find it completely amusing. It makes reading papers a bit easier in my day. ^_^

Does P-chem get harder before it gets easier? it's bad enough we have to practically teach ourselves. D:

Also, i heard that chemistry grad students tend to get 'free rides'. i was wondering if this was for the most part true ,because i'm going to be in enough debt when i graduate. D:
