An prototype machine developed by Scinomix to automatically transfer DMPD samples from cartridges to 96-well plates for further extraction. Suitable for analyzing large quantities of samples.

Automated DMPD Sample Transfer 

A tool to manually transfer dried matrix paper discs from cartridges to a 96-well plate for extraction.

Vacuum Tweezer

A glass capillary with fixed volume (5µL or 10 µL) attached to a micro plastic pipette.  It can be used to put liquid samples onto paper discs in DMPD cartridges.  It is also a perfect tool to collect samples for whole blood microsampling.

SurePet fixed-volume capillary micropipette

DMPD derived from pre-cut Dried Blood Spots (DBS) to improve DBS performance and data quality.  DMPD cartridges were developed in 2010 and have been used in preclinical and clinical studies to analyze blood, plasma, and other biological liquid samples.


Unlike DBS, the sample volume is controlled by either fixed-volume spotting or paper disc saturation (a volumetric microsampling concept we used first). 


With fixed volume spots on a paper disc and whole spot extraction, the analysis results are accurate without effect from hematocrit variations.


A DMPD cartridge can hold 6 replicates of dried samples for repeated analysis.  Same high quality DBS paper may be used to maintain data quality.  However, per sample cost is significantly lower.
