Waters Oasis WAX Vac Cartridge 1 cc 30 mg Sorbent 30 um Sealed 70 Cartridges

The Waters 186002489 Oasis WAX Vac Cartridge is a solid-phase extraction (SPE) device meticulously engineered for the selective extraction and concentration of acidic compounds from complex sample matrices. These cartridges are precisely packed with 30 mg of Oasis WAX sorbent, a key component for their functionality, and are presented in a 1 cc format, optimized for specific sample volumes. The sorbent particles within the cartridge are characterized by a 30 µm size, which influences the efficiency and flow dynamics of the extraction process.

The Oasis WAX sorbent is a critical element, where WAX stands for Weak Anion eXchange. This sorbent is specifically designed to effectively retain negatively charged (anionic) compounds, making it a valuable tool for isolating acidic analytes like organic acids, sulfonates, and phosphorylated compounds. Solid-phase extraction (SPE) itself is a sample preparation technique widely used to isolate and concentrate analytes from complex matrices, such as biological fluids, environmental samples, and food products. This process effectively removes interfering substances, allowing for improved sensitivity and accuracy in subsequent analytical methods. The 1 cc cartridge format indicates the volume of the cartridge, directly relating to the amount of sorbent it contains and its suitability for processing specific sample volumes. The 30 µm particle size of the sorbent affects the flow rate and overall efficiency of the extraction process, influencing the separation and recovery of the compounds of interest.

These Waters Oasis WAX cartridges are indispensable tools in analytical chemistry laboratories, finding frequent application in areas such as pharmaceutical analysis, environmental monitoring, food safety testing, and clinical diagnostics. Their utilization helps to ensure cleaner samples and the generation of more reliable and accurate analytical results, contributing significantly to the quality and validity of scientific investigations.
