system employed was a Thermo Fisher UHPLC Dionex Ultimate 3000 (Germering, Germany).
In a 10-page paper submitted to the House committee on population and family relations, UPLC
said the lack of definition of these two grounds 'will lead only to misunderstanding of the law and laxity in dissolving marriages.'
Then the dried residues were reconstituted with 125 [micro]L of mobile phase and centrifuged at 15,000 rpm for 7 min at room temperature and then filtered using syringe membrane filters (13mm) kinesis to be ready for injection and analysis into the UPLC
To obtain accurate, valid, and optimal separation, the UPLC
conditions were investigated with regard to column, mobile phase (water-acetonitrile with different modifiers including acetic acid, formic acid, and phosphoric acid), detection wavelength (215, 230, 254, and 280 nm), and mobile-phase flow rate (0.5, 0.4, 0.3, and 0.2 mL/min)  The best UPLC
conditions were obtained from the ACQUITY UPLC
BEH C18 column, which had better resolution than the others.
Pfizer has also analysed these three batches of Infinitam by HILIC-UPLC, a method similar to the UPLC
method used by Miranda-Hernandez et al.
A 10 [micro]l aliquot was injected into the UPLC
The low-dispersion system design of Waters' UPLC
systems combines with solvent agnostic small particle column chemistries to deliver unprecedented high resolution SEC/GPC separations.

Waters' ACQUITY UPLC
M-Class System is a nano- to micro-scale UltraPerformance LC (UPLC
) system rated for 15,000 psi operation.
Three tenders for the supply of (a) chemicals to the subordinated main laboratories, (b) chemicals for the main laboratories of the Toxics Division (in charge of assessing fungicide toxics), also (c) a UPLC
liquid chromatograph instrument, also for the toxics laboratory.
The lab is equipped with the latest technology, an ultra-modern microbiological lab, a chemical lab with high precision equipments like ICP-MS, UPLC
MS, GCMS and experts with deep domain knowledge.
