Whatman™ filters for water testing
Water testing is essential for ensuring the safety and quality of water for human consumption and environmental and industrial applications, as well as for ensuring compliance with regulatory requirements. Accurate testing helps detect contaminants, measure chemical and biological components and maintain regulatory standards.
You can ensure that your environmental water testing meets the highest standards with Whatman™ filters, designed for precision and ease of use in a range of essential tests, including:
- Solids analysis
- Metals analysis
- Dissolved ions testing
- Dissolved organic carbon (DOC) content measurement
- HPLC, UHPLC, ICP-MS
- Microbiological analysis
Whatman™ filters are engineered to provide reliable results, even with challenging samples, to make each analysis quicker and more efficient. For example, Whatman’s 934-AH RTU glass fiber filters come prewashed and pre-weighed, saving significant time during suspended solids analysis.
For tough-to-filter samples, the GD/XP™ syringe filters, with an integrated dual-layer prefilter and a 0.45-µm membrane, streamline filtration while minimizing ion extractables, making them ideal for use in metal trace analysis by ICP-MS. Whether you're using Anotop™ IC, Puradisc™ Aqua 30, Spartan™, or Mini-UniPrep™, Whatman™ filters are designed to simplify your process and deliver precise results.
Whatman™ offers specific filters to guarantee reliable results and ease of use for analyses with critical samples. For example, the 934-AH RTU glass fiber filters are available prewashed and preweighed for considerable time savings when performing suspended solid analysis.
GD/XP™ syringe filters include an integrated prefiltration with dual-layer prefilter stack and one final 0.45-µm membrane to make the filtration of hard-to-filter samples easy. In addition, the pre-filter stack of polypropylene filters minimizes ion extractables, making these filters suitable for metal trace analysis by ICP-MS.
