Instead of punching blood spots the DBS Autosampler™ uses clamps and dried blood spots or dried matrix spots which are directly desorbed as a liquid sample for analysis. This enables a completely automated workflow for DBS analysis. Dried blood spot (DBS) sampling is an emerging technology for bioanalysis offering easy, convenient and cost-effective sample collection, transport and storage.

Features

Unique Flow-through desorption (FTD™) technology for sample prep and optional online coupling to (SPE)-(LC)-MS/MS
Option for mounting different clamp sizes for the desorption of different sized spots
Partial spot or full spot desorption
Automated internal standard addition (AISA™)
HotCap™ heated capillary for better desorption
Wash flow path with solvents and/or HotCap™
Standard 96 DBS card capacity:4 sample spots per card allows possibility of 384 samples

Specifications

Flow-through desorption concept (FTD™): Leak-tight clamp heads provide direct elution of DBS from cards without punching discs.
