Nexera XS inert
Ultra High Performance Liquid Chromatograph
For many biopharmaceuticals and medium-molecule drugs, it can be difficult to acquire reliable data using a typical HPLC system, due to adsorption caused by interactions with metal ions. That tendency is particularly true for molecules that contain phosphates, carbonyl groups, or other characteristic elements or functional groups, the adsorption of which can affect analysis in various ways, such as by causing poor peak shape or inadequate sensitivity. Therefore, to increase the sensitivity and accuracy of analysis, it is important to inhibit the adsorption of compounds to the system.
In addition to the standard Nexera models made with stainless steel for excellent pressure resistance, broad applicability, and robustness, a new bioinert model has been added to the Nexera series product line. Nexera XS inert UHPLC systems achieve a 105 MPa pressure capacity while inhibiting adsorption to metals by using PEEK or ceramic materials in flow channels where samples flow. They also offer excellent resistance to corrosion and a broad range of pH levels, meaning they can be operated reliably using mobile phases that contain high haloid salt concentrations or have extreme pH levels.

Nexera XS inert
The potential adsorption of an analyte onto wetted surfaces of UHPLC instruments poses some critical challenges when analyzing biomolecules. While elevated pressure tolerance is required to achieve optimal chromatographic separation through the use columns with a small particle size, the inertness of the wetted surfaces is also of the utmost importance as is resistance to corrosion due to the use of mobile phases with high salt concentrations and extreme pH values. The Nexera XS inert system offers the ideal solution for the separation of molecules by combining the elevated pressure tolerance of a UHPLC system with complete inertness of the sample flow path, ensured by the absence of wetted metal surfaces and offering ultra-high resistance to corrosion.

New Breakthrough in Biologics Analysis with Bioinert, Biocompatible and High-Pressure UHPLC
Modern biotherapeutics, such as monoclonal antibodies (mAbs), antibody-drug conjugates (ADCs), and nucleic acid drugs provide new modalities to tackle persistent health concerns. To ensure patient safety and therapeutic quality, ICH-Q6B requires biological products to be tested for impurities and or separated during manufacturing process to determine the level of impurities present. Most of these analyses are performed using ultra-high performance liquid chromatography (UHPLC). Using small particles, acid, buffer solutions, organic solvents, and high salt concentrations in standard UHPLC systems can lead to corrosion, accelerated wear, and diminished performance. Analyzing biomolecules by UHPLC also poses some significant challenges due to the potential adsorption of analytes onto the wetted surfaces of the instrument, especially stainless steel materials like needles, tubing, and flow cells. The Nexera XS inert system offers a perfect solution for biopharmaceutical analytical method development, method scouting and quality control by incorporating the high-pressure tolerance of UHPLC alongside complete inertness of the sample flow path, which is achieved by eliminating wetted metal surfaces and offering an ultra-high corrosion resistance for SEC, IEX, and HIC chromatographic methods.
