Agilent has released the 8850 GC #chromatography #chemistry agilent.com/en/product/gas-chr…

🧪 Now we’re talking – Episode 5:
Meet the gel permeation chromatograph! This machine helps us understand how big (or small) molecules really are 🧬 — and plays a key role in basic research at Hof University of Applied Sciences.

Picture of GPC and Johannes Küfner with short informations about the machine. The machine is supervised at the Institute for Circular Economy of Bio:Polymers (ibp) by Johannes Küfner and Benedikt Hiller, both research assistants, David Krieg, deputy research group leader and Lucas Großmann, deputy head of the institute.

Anyone who can read in *.raw chromatography files and save the chromatogram as a PDF file for us? #GCMS #LCMS #chromatography #chemistry #analytics #Xcalibur

chromConverter 0.7.5 is finally available on CRAN! Major changes since v0.2.1 include support for 10+ new file formats (Shimadzu LCD/QGD, Agilent D, Varian SMS, Allotrope ASM, ANDI MS/CHROM, mzML), parallel processing, and improved metadata extraction.

Scientists developed a method for purifying #proteins from cell extracts or cultures using short-wave #UVlight, which is invisible to humans. The technique is more efficient and gentler than previous methods: http://go.tum.de/385699

My first first-authored #scientific #publication as a former #postdoc at ICTA-UAB, published in #Journal of #Chromatography A one year and a half ago, deserves a #thread on #Mastodon as well!
We selectively extract #levoglucosan and its isomers from complex matrices, such as #sediments, for quantification by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)!

#TIL that the output of size exclusion #chromatography (sec) can be called an elugram, presumably derived from elution volume/time, and I love it so much #chemistry #chemiverse

This was my first time working with ube extract, and DANG is that stuff strong!

I was incredibly amused to find that when I wiped up some spilled extract with a damp paper towel, it did the same kind of chromatography as my fountain pen inks.

It's so pretty! I couldn't quite get it to show up right but I did my best to tweak it a little - the actual color is that vibrant shade of purple the camera can never quite capture.

@FaithfullJohn I, very successfully, used the cut and weigh method to quantify chromatographic peaks. In an attempt to increase the mass of each peak (and therefore, I reasoned, precision) I tried photocopying onto OHP sheets but quickly found the precision was worse... I figured the thickness of the OHP sheets was less consistent than paper. But this was 40 years ago...
