Benefits of Using laboratory Ashless Quantitative Filter Papers
Date: 2017-05-27

The purity of results plays an important role in all important industries that heavily depend on chromatography for their brand value as well as quality. In view of this, various filtration devices and aids have been designed to get the best results. Some of these, such as ashless filter papers, are ideal in scenarios where you would like to get better results in less time.
These filter aids can be used along with other filtration devices such as filter papers, and are not restricted by filtration levels, types or solvents. They are basically quantitative in nature and are used in areas where analytical filtering is required. They can be used for initial separation or further down the chromatography process for more minute and rigorous filtration systems.

Uses of Laboratory Ashless Filter Papers
These filter aids are especially useful in cases where there is a requirement to enhance filtration speed while also ensuring high levels of purity. These aids coagulate suspensions or precipitates on top of normal filter paper to form a thick retentive ‘prefilter’ layer, which can further be processed or removed.

Ashless quantitative filter papers are easily dispersible, and are therefore effective with different types of filtration tools and filter papers. They are also useful in the preparation of solvents for laboratory analysis and study.


Areas of Application
Using these filter aids is especially beneficial when there is a requirement for quick and precise filtration. The purity of these powders is similar to that of ashless quantitative papers with a minimum ash content of 0.007%.

Areas of application of these filter aids extend across industries in any area where there is a need for filtration and purification of solvents of any kind. They are a must-have for any industrial or laboratory process that requires high precision results in an efficient manner and in a relatively quick time.
