Aug 03, 2015 · Mass spectrometry: THC-COOH and methamphetamine. Xevo G2 Q-TOF and Xevo TQ-S tandem MS (Aijiren Technology Corporation) were used. MS parameters were optimized via a direct infusion of methamphetamine and THC-COOH (500 ng/mL in the initial mobile phase) separately at 10 μL/min (Table I I). This LC-MS-MS was operated at unit mass resolution (±0.7 amu FWHM).

Sep 03, 2021 · Liquid chromatography–tandem mass spectrometry (LC-MS/MS)-based approaches do not have these limitations, and therefore enable the assessment of a wide scope of compounds, including non-antibiotics.
A simple, rapid, and sensitive liquid chromatography (LC)/mass spectrometry (MS) method was established and validated for simultaneous quantitation of pyrazinamide, isoniazid, rifampicin, and ethambutol in human blood sample. Samples were pretreated by a single-step precipitation with acetonitrile. Chromatographic separation was achieved on XSelecT HSS T3 column by gradient elution with a

Large mouth or wide ID vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling. Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools.
LC-MS/MS analysis showed an LOD of about 1 ng/g of matrix, but the recovery was relatively low at 43.6%.20 The efficient extraction of various compounds from food matrices is dependent on the molecule’s structural features. Penicillin G features a labile β-lactam ring characterized by its susceptibility to ring-opening under various conditions
Sep 18, 2017 · Stock solutions of TCA standards were freshly prepared before each LC-MS/MS run. However, analysis was repeated with stock solutions kept at −20°C for 7 days, and no changes were observed. This is in accordance with a study carried out by Keevil and colleagues reporting that citric acid was stable at −20°C for 30 days [ 23 ].
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.
