DBS Autosampler™
Why Spark DBS Autosampler™?
Flow-through desorption (FTD™) technology
No disc punching
Dried matrix sampling
Automation of the entire workflow
DBS sampling on the spot
Our DBS Autosampler™ uses a leak-tight clamp to directly desorb dried blood spots or dried matrix spots as a liquid sample for analysis. Direct elution offers a consistent quality, while eliminating the inconsistency of manual disc punching or costly robotics. It also allows the option of online clean-up and analyte separation by SPE prior to analysis in an automated workflow. All in minutes, providing maximum sensitivity without any manual intervention.
Key features
FTD™ - Flow-through Desorption (US patent no. US 8586382 B2)
Direct elution of DBS from cards enables online clean-up and analyte separation by SPE prior to analysis in an automated workflow. Optional online coupling to (SPE)(LC)-MS/MS.
IVC™ - Intelligent Vision Camera
Camera designed for accurate spot positioning of DBS cards for direct, flowthrough desorption of bloodspots. Full image capture guarantees sample information storage, tracking and traceability.
AISA™ - Automated Internal Standard Addition
A specified volume of internal standard is loaded in a loop using an integrated mini-pump. It is added in the desorption phase using a high pressure dispenser.
Additional options
Our DBS Autosampler™ comes with multiple options like mounting different clamp sizes of 2, 4, 6 or 8 mm for the desorption of different sized spots. Seal filter paper cards are available up to pressures of about 200 bar (up to 100 bar for the 8 mm clamp). Besides barcode identification for 1D or 2D barcodes, full or partial spot desorption options are available for sample traceability.
