Replicate caffeine determinations on fortified latte style white coffee and Pepsi Max® gave mean recoveries of 93.4% (%CV = 4.1%) and 95.0% (%CV = 0.98%), respectively. No interferences were recorded from endogenous beverage components or from commonly occurring drugs, such as nicotine, ibuprofen, and paracetamol. The theoretical limit of detection (3 σ) was 0.456 μg/mL. The response was linear over the range 10 to 500 μg/mL ( R 2 = 0.996). A 5 μL aliquot was introduced to the thermal desorption unit, dried, and thermally desorbed to the GC/MS. Using a pyrolysis-gas chromatography mass spectrometry system, the conditions required for the direct thermal desorption-gas chromatography mass spectrometry (TD-GC/MS) determination of caffeine were optimised. Nevertheless, the app gets the job done.An extraction-free method requiring microliter ( μL) volumes has been developed for the determination of caffeine in beverages.
On the other hand, Fast Chromatogram Viewer has not been updated for a pretty long time.
It runs on low CPU and RAM, so it doesn't affect the overall performance of the PC. There were no stability problems in our tests, so the program did not hang, crash or pop up error dialogs. You can also disable skins, adjust the main frame's opacity, and turn off the embedded file system. Change some program options easilyįast Chromatogram Viewer can be asked to automatically run at every Windows boot until further notice, as well as to minimize to the system tray area.
It is possible to trim the ends by setting the number and threshold for the section to keep, along with the window length and trimmed ends color. Examine Chromatogram files and configure settingsĪ graphical representation is shown on the bottom part of the screen, which can be easily navigated by moving a slider and zooming in and out. As far as the interface is concerned, Fast Chromatogram Viewer is packed in a seemingly outdated window with a neatly organized layout, where you can use the Explorer-based folder structure to navigate directories and open Chromatogram files. The entire setup operation takes little time and effort. It comes loaded with a few configuration settings that should be easy to figure out, regardless of your previous level of experience with such tools. Fast Chromatogram Viewer is a simple-to-use Windows program designed to display the content of Chromatogram files, namely those with the SCF, ABI, AB1, AB extension.
