AssayMAP cartridge overview
This topic describes the AssayMAP cartridge, cartridge rack, and receiver plate.
Description
The AssayMAP cartridges are microchromatography cartridges for small-scale sample
preparation. Each cartridge features a 5-µL bed that is packed with chromatographic
resin to support a variety of applications. Liquid can be aspirated or dispensed through
the packed resin in the cartridges. The AssayMAP Bravo Platform provides the
precision flow-rate control required for aspirating or dispensing the fluid through the
packed resin in the cartridges.
Cartridge anatomy
The following figure shows the parts of the cartridge.

Item Part Description
1 Sample
cup
The top part of the cartridge that mounts on the probe.
Note: When the cartridge is not mounted on a probe, the
sample cup can hold up to 200-µL of liquid.
2 Inlet seal The tapered seal at the top of the packed resin bed. When the
probe is inserted into the cartridge, the tip of the probe
engages the inlet seal. This configuration enables the Bravo
96AM Head probe to make or break a fluid-tight connection
between the packed-resin bed and the liquid inside the
syringe.
3 Resin bed The part of the cartridge that is packed with 5-µL beaded
resin. The bead size can vary depending on the assay (20 µm
to 100 µm).
