Analysis of Pesticides in Kale

A SLE application for acids (THC-COOH), neutrals (barbiturates), and bases (Norbuprenorphine and Buprenorphine) from a urine matrix containing β-glucuronidase followed by two LC-MS/MS methods.


Acids, Neutrals and Bases Using Novum Simplified Liquid Extraction (SLE)

Estrone, beta-estradiol, and estriol were derivatized from plasma using Novum PRO 96-Well Plates SLE for less background noise and cleaner samples post sample preparation.


Separation of Low Level Estrogen Analytes from Plasma by LC-MS/MS Analysis in Conjunction with Novum PRO Simplified Liquid Extraction (SLE)

This application focuses on developing a rapid SPE and LC-MS/MS method for the quantitative analysis of uracil and its two homologues from human serum


A Fast SPE Method for Uracil, 5,6-Dihydrouracil and 5-Fluorouracil from Human Serum by LC-MS/MS v2

Testosterone was isolated from plasma using Novum PRO 96-Well Plates SLE sample preparation.


Isolation of Low Level Testosterone from Plasma by LC-MS/MS Analysis in Conjunction with Novum PRO SLE

Analysis of GHB demands for an analytical procedure that is quick, efficient, and one that preserves the authenticity of the sample. A method for the quantitation of GHB in human blood is presented using SPE with LC-MS/MS analysis.


Analysis of Gamma-Hydroxybutyrate (GHB) in Whole Blood Using Quicker SPE and LC-MS/MS v2

In this application, an SPE method is implemented for a panel of pain relievers to produce acceptable results to offer an alternative solution for high recoveries and to reduce matrix effects.
