Efficient Automated Extraction

Efficient Automated ExtractionBooth 2449. The MultiPurpose Sampler XL (MPS XL) from Gerstel is an efficient sample preparation robot that performs various liquid handling techniques, as well as sample cleanup, such as SPE using standard dimension cartridges or the automated disposable pipette extraction (DPX). DPX is a fast SPE technique used for applications including drugs of abuse, therapeutic drug monitoring, comprehensive screening, pharmacology studies (NNK), and pesticides in fruit and vegetables.

Based on SPE devices, DPX requires little eluent, effectively providing a concentration step. With DPX, pipette tips incorporate loosely contained sorbent material, which is mixed with the sample solution. Turbulent air bubble mixing creates a suspension of sorbent in the sample, ensuring optimal contact, high recovery and extraction in 30 sec to a few minutes. Up to 98 pipette tips with loosely contained sorbent material are used, enabling automated cleanup of as many samples. Conditioning is generally not required, reducing solvent consumption and improving throughput.
