Online Monitoring System - Nutech
VsCMS 6600 VOCs – For 117 VOCs Target
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.
Detection Method: GC-FID/MS

Compounds Measured: C2~C12 VOCs
System Drift: 24-h concentration drift: ±1nmol/mol; long time concentration drift and retention time
drift: FID concentration drift ≤15% for 30d continuous operation; retention time drift≤0.5min.
Resolution: Resolution of cyclopentane and isopentane, 2,3-dimethylpentane and 2-methylhexane,
and o-xylene and styrene≥1.0.
Clock Error: The instrument is tested for 6 hours under normal working conditions and the clock
error is ±20s. The instrument is tested for 6 hours when the IPC is powered off 3 times in total and
the clock error is within 2min.
Standard Curve: The correlation coefficient of the standard curve of the target compound is ≥0.98;
use the standard curve to calculate the lowest point concentration, and the relative error between
the measured average value and the standard value is ≤15%.
Nutech 6600 Preconcentration System
1. The unique low temperature (-30°C) preconcentration technology effectively concentrates the
target compounds to be measured and realizes rapid thermal desorption, which greatly improves
the lower detection limit and meet
