Quality under control

Proven Performance. Confident Results.

Critical decisions are often based on the results of your analytical testing. Confidence in those results comes from using products that are proven to perform as expected, even with samples as small as 25 µL. Over thirty years ago, Pall Laboratory revolutionized sample preparation for analytical chemists with the development of the Acrodisc® syringe filter. Today we produce high-quality filters for sample preparation and dissolution testing that meet the unique requirements of every lab we serve. 

 

Sample and mobile phase filtration are simple, economical practices that serve to extend the life of consumable HPLC parts, decrease system wear and tear, and preserve the integrity of the HPLC system. Serious problems in HPLC can be avoided by being alert to preliminary warning signs and performing routine maintenance. Most HPLC part replacement tasks, such as changing pump seals, are readily recognized as necessary maintenance; however, mobile phase and sample filtration are also maintenance practices. Routine sample and mobile phase filtration are simple, inexpensive, and convenient ways to decrease HPLC problems.

HPLC & UHPLC sample preparation

A filter for HPLC applications is designed to increase accuracy by removing unwanted particles. However, the wrong filter can be a source of contaminants in the form of extractables that elute into the sample from the filter device. These undesired artefacts can jeopardize analytical results. Some extractable concerns include coelution, false quantitation, and extraneous peaks

LCMS sample preparation

In analytical sample preparation, extraction and leaching of chemical compounds from filters are major concerns, particularly when using liquid chromatography mass spectrometry (LCMS) for analysis. LCMS has gained popularity due to its versatility and superior sensitivity for both qualitative and quantitative analyses.

IC sample preparation

We certify our Ion Chromatography (IC) Acrodisc syringe filters have been tested using a highly sensitive IC protocol to monitor inorganic extractables. For ion chromatography applications, only the IC Acrodisc (PES) syringe filter is certified for low levels of inorganic extractables. Actual background levels of filter extractables are typically less than 20 ppb for chloride, 6 ppb for nitrate, 1 ppb for phosphate, and 10 ppb for sulfate.

Mobile phase filtration

By filtering mobile phase, analysts can reduce debris capable of plugging the sinker and column frits, causing contamination, damaging pump valves, blocking capillaries, causing poor peak performance, and contributing extra peaks and excessive chromatographic noise.
