DBS Autosampler™ Direct DBS/DMS elution without manual intervention

Dried blood spot (DBS) sampling is an emerging technology for bioanalysis, offering easy, convenient cost effective sample collection, transport and storage. Our revolutionary DBS autosampler™ has set a new standard for bioanalysis. It maintains the integrity of the sample through automation using our unique direct elution FTD™ technology for sample preparation. Can you only imagine its potential?

Our revolutionary direct elution FTD™ technology sets a new standard for bioanalysis.

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.
