Trace Nitrogen / Sulphur / Chlorine

TSHR_Nexis_TX_Closed.336b.png

The NEXIS Total Nitrogen / Sulphur / Chlorine analyser is a horizontal oriented combustion analyser with high modularity and advanced detectors to measure simultaneous trace level nitrogen/sulphur and separate chlorine concentrations in a wide range of liquids, solids and LPG/Gas sample types. The NEXIS TN/TS/TX analyser configuration detects these substances through a uniquely high effective NEX-Z combustion tube design that includes Ultra Violet Fluorescence (UVF), Chemiluminescence (CLD) and micro-coulometric (MCT) detectors. The NEXIS TN/TS/TX model is designed to facilitate high sample throughput by optional addition of the AS120 liquid autosampler that will support both syringe and boat introduction methods with high performance and reliability. This solution provides a fully automated trace level Total Nitrogen/Sulphur analyser, which can be extended with heated sample tray capability. For Gas and LPG samples the NEXIS TN/TS/TX analyser can be connected to a NEXIS GM module to facilitate these kind of samples with fast connectivity and ease of use operation through NEXIS LINK software. The main instrument is manufactured by TSHR, whilst the autosampler is manufactured by EST Analytical. Their website can be found here for further information.

The NEXIS VP Total Nitrogen/Sulphur Analyser is the most sensitive and reliable vertical combustion analyser to detect precisely, from ultra trace to high ppm level, total sulphur concentrations in an extensive range of liquids and LPG/Gas samples. The NEXIS VP model TN/TS analyser configuration detects simultaneously these substances through a uniquely high effective NEX-Z combustion tube design that includes a Ultra Violet Fluorescence (UVF) and Chemiluminescence (CLD) detectors. The NEXIS VP Total Nitrogen/Sulphur Analyser is designed to facilitate high sample throughput by the AS/120 liquid autosampler through syringe introduction methods with optional heated and cooled sample trays. For Gas and LPG samples the NEXIS VP TN/TS analyser can be connected to a NEXIS Gas Module (GM) to facilitate the safe and automated sampling and analysis process for these type of samples with fast connectivity and ease of use operation through NEXIS LINK software.
