Analytical QC

We are here to support your each and every need. Our knowledgeable team will help you achieve accurate and dependable results to ensure the best performance.

Quality Under Control

Proven Performance. Confident Results.

Proven Performance. Confident Results.

 

Critical decisions are often based on the results of your analytical QC testing. Confidence in those results comes from using products that are proven to perform as expected, even with samples as small as 25 µL. In 1974, Pall Laboratory revolutionized sample preparation for analytical chemists with the development of the Acrodisc® syringe filter. Today we continue to produce high-quality filters for sample preparation and dissolution testing that meet the unique requirements of every lab we serve.  

 

We continue to revolutionize the industry with new products and solutions to meet your laboratory’s ever-changing needs.  Today we have a wide variety of Analytical QC membranes including our new wwPTFE membrane “the next generation in universal membrane filtration” as well as Nylon, PVDF, hydrophobic PTFE membranes and more.  Our newest wwPTFE membrane comes in a variety of sizes to accommodate sample volumes from 25 µL up to 150 mL.  Providing your laboratory with the ability to process single samples with the new Pall Laboratory Acrodisc One™ syringe filter, small volumes with the Nanosep® spin device or up to ninety-six samples with the Acroprep™ Advance filter plate

 

 

The Pall Laboratory wwPTFE Membranes: 

 

 

  • Extend column life up to 52 times 
  • Reduce contamination with up to 24% less filter extractables than the competition 
  • Process single samples or up to ninety-six samples at once 
  • Simplify your sample preparation, saving time and money

Effects of filters on HPLC column life following injections of unfiltered and filtered 0.05% latex sphere suspensions. With unfiltered samples, the column failed due to plugging after 19 injections. Samples passed through Competitor filters plugged the columns after 500 injections. No increase in backpressure was observed after 1000 injections of samples filtered with Pall Acrodisc One syringe filters.

Acrodisc One Technical Guide

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.
