VOCs Analysis Methods
VOCs Analysis
Lab Online Portable
VOCs can be analyzed by lab instruments, online instruments and portable instruments. Nutech
is the only company who can provide VOCs analysis solutions & products for lab, online and
portable applications.
Nutech 3000 Portable THC & NMHC Analyzer is the latest generation product for portable VOCs
analysis and we’ve made many improvements based on the existing products on the market.
The Necessity for a Portable VOC Analyzer
⚫The gas sample at emission source is hot and moisture. It is evitable to cause sample loss,
adsorption and deterioration during sample collection and transportation for lab analysis
and thus the test results will be affected.
⚫Lab analysis can’t deliver timely results and thus its is not applicable for emergency
monitoring.
⚫The lab analysis is labor intensive with samples to be collected, transported and analyzed.
⚫Online analyzers are permanently installed and need regular maintenance which doesn’t fit
for applications that only require occasional / periodical / emergency monitoring.
Occasional Monitoring Periodical Monitoring Emergency Monitoring

Why List NMHC as an Monitoring Target
•TVOC can be represented by THC (CH4+NMHC) or NMHC.
•CH4 is a non-toxic and unharmful gas and it accounts for the major part of THC. NMHC is the
harmful & hazardous part in THC. Thus, to analyze toxic VOCs, NMHC is a more precise target
than THC.

NMHC
NMHC is a more precise representation of TVOC
Typical Applications
•Environmental inspection and law enforcement by government regulator
•VOCs testing by commercial testing companies
•Effectiveness evaluation of VOCs control measures
•Self-inspection of VOCs emissions from chemical, printing and dyeing, spray painting
companies
•On-site detection and supervision of kitchen oil fume
•On-site comparison with the results of online VOCs analyzer to determine whether the online
analyzer’s result is accurate.
•VOCs emission detection of combustion device exhaust

⚫Government environment protection regulators. They can bring this instrument to raid a
suspected over-emission site and do test on-site to see if there is an over-emission. If yes, they
can fine the owner. They can also use this instrument to do a before and after comparison to
evaluate the effectiveness of their VOC control measures .
⚫Polluters/factories. Some polluters are required to install online analyzers to deliver
continuous real-time test results all year long. But many polluters only need to perform
periodical (weekly, monthly, quarterly ect) or occasional VOC testing. In this situation, a
portable analyzer would be more applicable than an online analyzer.
⚫Commercial testing companies. They can use the portable VOCs analyzer to provide on-site
VOCs testing service.
⚫Research institutes. They can use this instrument on their VOCs research projects.

Technology Principle
TVOC can be represented by THC or NMHC. The Nutech 3000 adopts catalytic oxidation + double
FIDs technology to simultaneously analyzes THC & NMHC.
The sample gas is introduced to the analyzer by 2 channels. FID 1 analyzes the concentration of
THC (total hydrocarbon) of the gas sample in channel 1. And the catalytic oxidation module
oxidizes the NMHC (non-methane hydrocarbon) into CO2 and H2O in channel 2 and thus FID 2
only analyzes the concentration of methane. The concentration of NMHC can be calculated by
concentration of THC subtracts the concentration of methane.
Concentration of NMHC = Concentration of THC –Concentration of CH4
Analyzed by FID 1 Analyzed by FID 2

Technical Data
Standard Configuration
Instrument main unit (including catalytic module, metal hydride cylinder), sampling tube
(including probe, filter device), Microsoft Surface GO tablet, backpack.
Lightweight & Integrated Design
•Highly integrated design to ensure the total weight within 12KG (including catalytic module,
metal hydride cylinder, battery, zero air generators, etc)
•Analyze THC & NMHC in one single unit.
•Equipped with a backpack and a handle, which can be easily transported and put into use by
one person.
Easy to Use
•Large-capacity battery (45Ah) power supply, which can run for a long time even without
utility power on site.
•Operated by a detachable touch screen tablet with Wi-Fi communication and a user-friendly
interface. Users can control the instrument and read test results within 50m (33ft) of the
site through the detachable tablet.
Features

High Test Efficiency
•New catalyst is used to achieve high conversion efficiency (≥95%)
•Double FID design and can measure both THC & NMHC continuously at the same time
without the need to switch gas flow. It can deliver NMHC test results as fast as every second.
•Fast gas path cleaning speed.
Most Accurate Test Result
•From the sampling tube to the FID detector, the whole process is high temperature heating
to avoid condensation loss of high temperature and high humidity gas samples.
•The sampling flow path is silanized (a special surface treatment technology to make the
surface utmost inert), resistant to high temperature and corrosion, and contains a filter
device to effectively filter particles to avoid sample contamination and adsorption.
•High precision EPC and FID are adopted to ensure accurate flow control and accurate
measurement.
•Support automatic & manual purge function to keep the system clean and thus deliver more
accurate test results.
Powerful & Easy Data Processing
•Data file automatic recording and storage, historical data query, reprocessing and printing
functions.
•Test data can be exported in Excel file.
Lowest Running Cost in Its Kind
•H2 is supplied by mini built-in metal hydride cylinder with very low pressure and thus is safe
and easy to handle and transport. The metal hydride cylinder is recyclable.
•Zero air is supplied by internal pump. No need disposable zero air bottle.
•Also support external gas cylinder
Wide Applications
•Applicable in VOCs measurement in stack (high concentration), inside the factory (medium
concentration), outside the factory/fence line (low concentration).
