Filtry strzykawkowe Anotop do chromatografii IC
Niesterylne filtry strzykawkowe Whatman Anotop do chromatografii jonowymiennej (IC) są wyposażone w nieorganiczną membranę Anopore umieszczoną w obudowie z polipropylenu.
Whatman™ Anotop 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.
