The positive samples were sent for further analysis using HPLC-MS
at Eurofins Analytical Laboratories, Inc.
A 10 [micro]L aliquot of each sample was injected into the HPLC-MS
Today, high-throughput HPLC-MS
for structure confirmation allows acquisition of hundreds of spectra per instrument per day.
analysis was done on a HPLC system which consisted of a Spectra System SN4000 interface, a Spectra System SCM1000 degasser, a Spectra System P1000XR pump, a Spectra System AS3000 autosampler, and a Finnigan LCQ Classic ion trap mass spectrometer in positive ion mode (all Thermo, San Jose, CA, USA) equipped with a SPD-10A UV-vis detector (Shimadzu, Kyoto, Japan) and Xcalibur 2.
Chromatography-grade acetonitrile used for HPLC-MS
analysis were purchased from Alltech Scientific (Beijing, China).
Contract award notice: The subject of procurement is the supply of 1 pc new, unused sets liquid chromatography coupled with triple quadrupole with one control system software (hereinafter the "report HPLC-MS
/ MS") meets the technical specifications required by the contracting authority, its accessories and technology.
