Macherey Nagel have expanded the HPLC product line to include the NUCLEODUR® PFAS, 3 µm HPLC and UHPLC columns
Polyfluoroalkyl substances (PFAS) are a group of highly stable synthetic organic compounds which are used in a wide variety of industrial and commercial applications as additives in consumer products such as fire-fighting foam, fiber coating, cookware, paper finishing and food packaging to name a few. Within mainstream media they are often referred to as "forever chemicals". These substances strongly bioaccumulate within our natural environment and have become ubiquitous throughout the world since the 1940's.
NUCLEODUR® PFAS, 3 µm HPLC columns provide a solution for analysing and detecting these substances. Macherey Nagel columns show a high batch-to-batch reproducibility which make them well suited for LC-MS/MS analyses due to low bleeding characteristics. The new columns are available in a 2 mm ID and 100 or 50 mm lengths. Each column is accompanied by documentation which certifies and identifies each column to it's respective batch for PFAS analyses in the laboratory.
NUCLEODUR® PFAS Delay, 5 µm columns provide high retention for PFAS compounds and are used to retain PFAS contaminants from the HPLC system, which could otherwise falsify the sample to be analysed. For this purpose the NUCLEODUR® PFAS Delay column is connected in flow direction between the mixing vessel and the sample injector, as seen in the flow diagram below.
Stainless steel HPLC columns for analytical or preparative applications are an ideal choice for your daily labwork.
NUCLEOSIL HPLC phases have gained wide acceptance as routine chromatographic packings for differing fields in modern chromatography. It is one of the first spherical silicas used in HPLC and is a reliable choice for routine analyses.
NUCLEODUR silica is an ideal base material for modern HPLC phases. It is the result of MACHEREY-NAGEL's pioneering research in chromatography for almost 50 years. NUCLEODUR HPLC columns with 1.8 µm particle size for increased separation efficiency are used for UHPLC applications.
Due to core-shell technology NUCLEOSHELL columns provide efficient separation results with a comparably lower back pressure to fully porous materials.
