PromoChrom - SPE Mini-Disks for Environmental Sample Extraction

SHARE
PromoChrom Technologies has innovated Mini-disks to capture the advantages of SPE disks, particularly in extraction speed, while addressing their limitations in solvent consumption and automation. These Mini-disks are designed with a format size similar to a 30-mm syringe filter and provide an increased cross-section area five times that of a 6-mL SPE cartridge. This larger cross-sectional area, combined with optimized sorbent properties, allows Mini-disks to operate at higher flow rates compared to traditional SPE cartridges. Their compact size facilitates seamless integration with cartridge-type SPE instruments and minimizes solvent usage. Mini-disks are also compatible with standard luer slip connections, making them suitable for automated SPE systems and vacuum manifolds. Additionally, they feature narrow particle-size distribution sorbent material composed of 25-um spherical beads, enhancing sample capacity and reducing resistance to liquid flow. The anti-clogging frit technology further improves tolerance to particulates, making these Mini-disks a robust solution for solid phase extraction applications, including the automated extraction of TCLP semi-volatiles targeting basic, neutral, and acidic compounds.

Time Saving

By allowing much higher flow rates than SPE cartridges, extraction time can be significantly reduced.

System Compatibility

The diameter of the Mini-disk measures only 30mm and is packaged to fit standard luer slip connections, making it suitable for cartridge-based automated SPE systems and vacuum manifolds.

Narrow Particle-size Distribution
The sorbent material for the Mini-disks are made up of 25-um spherical beads with very narrow size distribution. This smaller bead size increases sample capacity while the uniform distribution offers lower resistance to liquid passing through the disk.
Clog Resistance

Our Anti-clogging frit technology is also applied to the Mini-disk for further tolerance to particulates from sample matrices
