I think I may have answered you on the Seachem Forum as there was recently a question there about the Aquatech 5/15 - Rick?...
Seachem Matrix is a dime size porous bio-media with micro/macro pores that serve as a platform for beneficial bacteria. They also market a smaller size as De*Nitrate.
The claim is that aerobic bacteria to process/oxidize ammonia and nitrites on the surface and anaerobic bacteria will populate internally to process nitrates. The latter becomes difficult. I have an AC70 filter running now filled completely with a mix of Matrix and De*Nitrate. You really won't be able to effectively use Matrix in an Aquatech 5/15.
Seachem Purigen is a synthetic polymer resin that adsorbs dissolved organic compounds, preventing them from degrading further and producing ammonia. It aids in producing crystal clear water while removing DOCs from the water column. This media begins creamy white and slowly turns quite brown as it traps organics (exhausts). However, it can be regenerated several times using a 50/50 bleach/water mix, followed by de-chlorination.
I am currently using two 100ml pouches in my 60g tank.
I believe you could slip a 100ml pouch in front (tank side) of the Aquatech 5/15 cartridge.
Like most cartridge HOB's, the Aquatech 5/15 is not really designed for anything other than it's cartridge. You might get a little creative, but it's still limited.
