Examples of LC-MS in a sentence

  • THC (cannabis) is treated as a controlled substance and will be tested through an FDA-approved oral fluid (saliva) testing collection device at a screening level of 25 ng/ml and a confirmation level of 10 ng/ml (LC/MS).

  • Test equipment: LC-MS Required limit value: Should not be present in products.

  • Moreover, with the smaller inner diameter columns that are typically used (75 μm to 1 mm-I.D.), micro-flow LC-MS provides higher sensitivity using lower amounts of sample.

  • However, due to the small inner diameter of the spray emitter, the LC tubing, and the column, the overall stability of such chips remains a challenging aspect in nano-flow LC-MS, contrary to conventional methods with 2.1-mm columns and milliliter range flow rates 22,23.
