LC-MS definition
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.
HP is a leader in developing low-cost mass spectrometers and technology for the ionization/interface stage of LC/MS systems.
Bruker also will manufacture CD ROMs or discs containing the software for the following optional products, which HP may purchase from Bruker: LC/MS Dissect, Library Search, and stand-alone data analysis.
The Core scientists provide a wide range of services and scientific/technical supports including consultation, design of the bioanalytical experiments, standard sample preparation, and processing (e.g., digestion of solid sample by nitric acid for ICP-MS, trypsin digestion of protein for bottom- up LC-MS proteomics), data acquisition, standard data analysis, drafting experimental section for publication upon request, GC-MS training, as well as new method development upon approval by the Core Director.
To have an unbiased view of all metabolites, HPLC, GC-MS, LC-MS and NMR spectroscopy based metabolomics to detect the compound or compounds responsible for the inhibition of the growth of fungi or inhibiting insect foraging seems very useful.
Examples of issues that are not encompassed in the Support are requests for advice on LC-MS conditions, acquisition method customization, ▇▇▇- ple preparation, experimental design, etc.
HPLC methods comparability Requirement: Samples from Radius (if needed) Timeline: 4 weeks Deliverable: Comparability report between 3 HPLC methods, including LC/MS identification of impurities.
