Filtry strzykawkowe Anotop IC

Filtry strzykawkowe Anotop 10 i 25 IC przeznaczone są do przygotowania próbki przed chromatografią jonową.
Whatman™ Anotop 10 and 25 IC syringe filters are designed for efficient filtration prior to ion chromatography.

• Each batch is certified for low levels of anion leaching in ion chromatography (IC) filtration
• Filters large particulates, extending column life and increasing peak resolution
• Narrow pore size distribution and capillary pore structure for consistent results from a syringe filter

Anotop for ion chromatography analysis
Ion chromatography analysis often benefits from filtration as a sample preparation step. When done correctly, filtration can remove particles that might otherwise cause unwanted peaks or damage the chromatography column. Therefore, an ion exchange chromatography method should include a high-quality syringe filter.

Anotop IC syringe filters have an aluminum-based Anopore membrane that minimizes anion leaching during ion chromatography filtration. Leaching is validated at 10
30 ppb for major anions such as fluoride, chloride, bromide, sulfate, nitrite, and nitrate (see product data).

Aluminum-based Anotop syringe filters
Anotop syringe filters are a versatile solution for most organic solvents and aqueous samples. Aluminum-based Anopore membranes are inorganic and designed to be inert and function in wide temperature ranges.
