NEXIS VP – Total Nitrogen / Sulphur Analyzer

The NEXIS VP is the most sensitive and reliable vertical combustion analyzer that detect precisely, from ultra-trace to high ppm level, simultaneous Total Nitrogen / Sulphur concentrations in a wide range of liquids and LPG / Gas samples, meeting stringent compliance to International ASTM, ISO, DIN, EN and UOP regulatory methods.

The NEXIS VP model TN/TS analyzer configuration detects these substances through a uniquely high effective NEX-Z™ combustion tube design that includes high quality UV Fluorescence (UVF) and Chemiluminescence (CLD) detectors. The NEX-Z™ combustion tube in combination with the reliable temperature controlled sample inlet port is suitable for the whole range of liquid hydrocarbon samples without the need of special catalyst or inlays.

The NEXIS VP is designed to facilitate high sample throughput by the AS120 Liquid Autosample through syringe introduction methods with optional heated and cooled sample trays. For Gas and LPG samples the NEXIS VP TN/TS analyzer can be connected to a NEXIS Gas Module (GM) to facilitate the safe and automated sampling.
