Application Notes: General

An isocratic HPLC method for the analysis of aflatoxins. Uses the DFL-10 (filter fluorescence detector) with a photochemical reactor to improve sensitivity.

Select the proper manifold for your individual microbiological testing procedure, choose between reusable and single use funnels or filtration units, and decide between different sizes of manifolds and enjoy the manifold that adapts to your needs.

Automatic membrane filter dispensing either by touch of a button, hands-free motion detection or by using a foot switch minimize risks of secondary contamination.

Innovative design features, coupled with the largest surface areas and fastest flow rates make Minisart® syringe filters the ideal choice for your syringe filtration needs.

Safety first: Whatever beverage you produce – beer, wine, bottled water, softdrinks, or spirits - you cannot afford to compromise on quality. Sartorius helps you meet the industry’s growing challenges now.

This application note describes the improved identification of pharmaceutical low-level impurities when using SFC and UHPLC as orthogonal separation modes.

Discover an automated sample preparation system that effectively and efficiently extracts diquat and paraquat from drinking water via EPA Method 549.2.

Teach a virtual chromatography lab with LC simulation software. See how one chemistry professor replaced hands-on labs with online experiential learning.

From siRNA to mRNA to DNA, separating full length product from impurities can be challenging. Taking into consideration the nature of the oligonucleotide you are interested in, you will be able to make informed choices about what approach to use to characterize or purify your molecule.

This application note describes the company’s range of oligonucleotide columns and oligonucleotide standards.

This application note demonstrates the suitability of the company’s stationary phases to separate deprotected RNA and DNA oligonucleotides of different sizes.

A method using the company’s system to purify long-and short-term oligonucleotides is described.

This application note demonstrates direct ion-pair reversed-phase online desalting using 2D -LC for the analysis of oligonucleotides.

Polymeric strong anion exchange methods such as PL SAX are suitable for anion exchange and purification of oligonucleotides. At elevated temperatures, enhanced mass transfer increases the resolution for larger oligonucleotides. Working at higher PH values enables resolution of phosphodiester and phosphothioate forms of the oligonucleotide.
