Additional Information
Sep-Pak XPoSure Plus Short Cartridge, 350 mg Sorbent per Cartridge, 500-1000 µm, 20/pk Quantify formaldehyde concentrations in the workplace and indoor air within the range of 0.001 to 5 parts per million (ppmv) using the reproducible and convenient Sep-Pak XPoSure Plus Short Cartridge. The Sep-Pak XPoSure Plus Short Cartridge is an invaluable piece of lab equipment that traps aldehydes in the air by reacting them with acidified 2,4-dinitrophenylhydrazine(DNPH), forming stable hydrazone derivatives. Aldehydes and ketones react in situ to form the hydrazone derivatives. The derivatization reaction takes place during sample collection. HPLC method is used to, later on, elute and analyze the derivatives. The Sep-Pak XPoSure Plus Short Cartridge is suitable for the analysis of particles sized between 500 to 1000 µm and pore size 125 Å. The cartridge uses the highest quality packings that are designed and specially made for sample preparation. You can leverage the clean, dry reproducible activity and capacity with optimal surface area, pore size, and particle distribution. With the Sep-Pak XPoSure Plus Short Cartridge, you can be certain that the product integrity, packing activity, and purity are maintained until the package is opened as the cartridges are sealed in specially designed, non-contaminating poly-foil pouches. While enhancing convenience for manual operation, the Sep-Pak XPoSure Plus Short Cartridge is also suitable for robotic applications. This is because the Sep-Pak XPoSure Plus Short Cartridge comes with a touch shell, large outlet flange, and precise axial alignment. You may also find the Sep-Pak Ozone Scrubber Potassium Iodide, Plus Short Cartridge, 1.4 g, 55 - 105 µm, 20/pk of interest that is specially designed for the analysis of carbonyl compounds in air samples but ensuring that any ozone interference is removed.

FAQ
How Can Analytes Be Isolated And Cleaned Up? To isolate and clean up sample components of interest, two general SPE strategies can be implemented. When the compounds of interest are present in levels too low for accurate and precise measurement, the retention-cleanup-elution strategy may be utilized. Through this strategy, concentration of dilute samples and trace enrichment of compounds is achieved.

When the required sample component is available in a higher concentration, the pass-through cleanup strategy may be chosen. It is noteworthy, however, that no sample enrichment occurs when a pass-through cleanup strategy is used.
