New Sample Preparation Findings Presented at MSACL

22 February 2017

Four posters were presented at MSACL in Palm Springs, CA, 22-26 January 2017. 

 

P154: Method Optimization for the Low Level Detection of Vitamin B7 from Human Serum Using UPLC-MS/MS Analysis

A new method for extraction of Vitamin B7(Biotin) using EVOLUTE® EXPRESS ABN.

P155: Simultaneous Extraction of Catecholamine and Metanephrines from Urine Prior to Analysis using LC-MS/MS

A ‘no blow down’ method using EVOLUTE® EXPRESS WCX.  Data from both the Load-Wash-Elute and standard SPE methods automated using Biotage® Extrahera™ are included. 

P156: Evaluation of three beta-glucuronidase enzymes to determine the best hydrolysis conditions for urine samples in clinical toxicology and pain management

This poster investigates the performance of three different beta-glucuronidase enzymes when used in conjunction with EVOLUTE® EXPRESS CX plates for extraction of a 56 drug panel from urine. The impact of a variety of hydrolysis conditions on recovery of parent drug is examined.

P157: Drugs of Abuse with Multivariate Intermolecular Properties Analyzed by Polymeric Mixed-Mode Cation Exchange

An investigation of into some of the key factors affecting analyte recovery and extract cleanliness when using EVOLUTE® EXPRESS CX plates for extraction of a 43 drug panel from hydrolysed urine, automated using Biotage® Extrahera™ sample processor.
