and preparation. “With MOMS, I can see a detailed report of patient information, the kit code, [and more],” explained the business operations manager at Natera. “Before, we weren’t tracking that information because sometimes, like with patient walk-ins, [testing] labs weren’t getting ...
Slight removal of the H2O by the polarising Ca2+ may have a buffering effect on the acid by pulling the equilibrium of the weak acid to the left hand side. The calcium citrate produced in citric acid solution will be a buffer and resist change in pH. This will slow the reaction down by...
For sample preparation of field collected material for an environmental metabolic fingerprinting approach a robust method was developed. The criteria for the choice of the most suitable extraction procedure of field-collected material were first of all reproducibility (the conservation of abundance/number ...
For HPLC analysis, methanol (≥99.8%) and formic acid (≥98%) gradient grade were from VWR (Lisboa, Portugal), BDH (Dubai, UAE), Probalo (Fontenay Sous Bois Cedex, France) and Merck (Darmstadt, Germany), respectively. Individual phenolic compounds standards were purchased from Sigma-Aldrich...
CO2 is captured during the adsorption step until the capacity of the sorbent is reached. In the desorption preparation step, the chamber is closed and, depending on the process, the pressure/temperature/humidity are changed to favor CO2 desorption. During the desorption step, the CO2 released ...

. The phosphate group—inherent with all phospholipids—acts as a very strong Lewis base that will interact strongly with zirconia atoms functionalized on the particle surface. Formic acid is a critical modifier used in the precipitation agent to improve the recovery of many analytes of interest (...
