The data analyzer/recorder attached to the machine draws a chromatogram (chart) with peaks corresponding to the relative amounts of the different chemicals in the sample.What is chromatography used for? “... the pigments separate themselves from top to bottom in different colored zones... such...
These seem to be exorbitantly high, compared with the smallest non-blank standard of 62.5, which gave me a well-behaved chromatogram. My boss wants to know why the LOD and LOQ are what they are compared to the 62.5 ppm standard, and I have no answers for him. I don't know if I'...
Other chromatography experiments can change these formula depending on what exactly they're measuring or considering as a result of the experimental setup. High-performance liquid chromatography (HPLC) uses a pump to transfer a liquid solvent under pressure through a column that absorbs the li...
You have been introduced to simple concepts on how to read a chromatogram. Please let us have your comments on the article and if you found it useful. Categories:Chromatography Dr. Deepak Dr Deepak Bhanot is a seasoned professional having nearly 30 years expertise beginning from sales and produ...
Interestingly, performing liquid separations at low pH (by addition of formic or acetic acid) is statistically better since sharper peaks can be obtained on the chromatogram. Formic acid and acetic acid are acid additives that are compatible with mass spectrometry detection, meanwhile, at the same ...
