Nutech Instruments Inc. products

The Nutech 8910 preconcentrator is the successor of Nutech’s classic model 8900DS. It has the most advanced hardware and software with unique features for the analysis of volatile organic compounds (VOCs) listed in U.S EPA Methods TO-14A and TO-15A. Functionality and longevity were the main goals in the development of Nutech’s ambient air preconcentrator.

The Nutech 3610 autosampler features 16 inlet positions that bring Nutech’s automated analysis capabilities to a wide variety of vacuum sampling canisters and Tedlar® bags. The 3610 autosampler easily connects to our 8900DS/8910 Preconcentrator for the automated analysis of VOCs in canisters with US EPA TO-14A, TO-15A and China EPA HJ 759-2015 and HJ 1078-2019 requirements.

Nutech 2203 precision static dilutor is suitable for diluting high concentration gas standards into low concentration working gas standards, making the process automated and reproducible. It is widely used in laboratory standard gas configuration.

The Nutech 7000 THC & NMHC Analyzer is applicable to laboratory analysis of methane and non-methane total hydrocarbons in ambient air or an industrial plant perimeter (sampled in Summa canisters).

The Nutech 3000 THC (Total Hydrocarbons) & NMHC (Non-Methane Hydrocarbons) Analyzer is suitable for portable monitoring of TVOC (Total Volatile Organic Compounds), CH₄ (Methane) and NMHC in stationary source emission and fence line.

NCMS 6300 is mainly used for the continuous monitoring of THC & NMHC in ambient air, which consists of sampling unit, analysis unit (including pretreatment), data collection and transmission unit, quality control unit, gas source unit and other auxiliary equipment. The analysis unit is the core module of the NCMS 6300 NMHC continuous monitoring system, which adopts the 6300 analyzer with unique LTP (Low Temperature Preconcentration) technology.

Nutech VsCMS 6500 VOCs Continuous Monitoring System – 57 PMAS Compounds Monitoring. For VOCs species analysis, Nutech provides continuous monitoring solutions based on different technologies (GC-FID, GC-FID/MS). The difference is that the analysis unit uses different analyzers. But because VOCs exist in ambient air at very low concentration (ppb or even ppt level), all these solutions need our innovative LTP technology to realize pretreatments like impurities removal and sample enrichment.

VsCMS 6600 consists of Nutech 6600 online Preconcentrator and Thermo Fiser Trace 1310 ISQ/FID (Agilent/Shimadzu/PE equivalent products are optional). Through the front-end low-temperature pretreatment like impurities removal, enrichment and concentration, the sample enters into the detector for analysis to realize online continuous monitoring of more than 100 VOCs.
