A supply business run by someone who has spent 14 years at the instrument

I am Dr. Nazmul Alam. I did my PhD in analytical chemistry at the University of Waterloo in Professor Janusz Pawliszyn's group, on quantitation in solid-phase microextraction. After that I spent 14 years running methods for a living: bioanalytical LC-MS/MS at contract research organisations, high-resolution MS at the Ontario Ministry of the Environment, natural health product QC, and method development in a cGMP environment.

Chromkit exists because of a pattern I kept seeing. Labs order consumables from a part number somebody copied off the last order, and instruments from whichever quote came back first. Then they spend two days chasing a problem the purchase created.

I once lost 2 days to a fronting peak. I swapped the column. Same peak. I re-prepped every sample. Same peak. The column was fine. My injection solvent was stronger than my mobile phase. Nothing I could have bought would have fixed that, and a distributor would have sold me another column.

So the order here comes second. Tell me the analyte and the matrix, and the first thing you get back is what you should be running. The quote follows that.

How Chromkit makes money

I do not hold stock. Products are shipped and invoiced by the manufacturer or distributor, and I earn a commission on what I refer. That is stated here rather than buried, because the entire offer depends on you trusting the recommendation.

It also means I have no inventory to clear. If the honest answer is that your current column is fine, or that the used system you are looking at is the wrong instrument category for your analyte, that is the answer you will get.

Method work and training

Method development, troubleshooting and hands-on HPLC and LC-MS training are separate, and they live at nalam.ca. Keeping them apart is deliberate. Advice you pay for should not be shaped by what somebody wants to sell you.
