- Model 109L - Heated Non Methane/ Methane/ Total Hydrocarbon FID Analyzer

From

0

The J.U.M 109L is a heated FID analyzer to continuously and simultaneously measure the Methane concentration, the Total Hydrocarbon concentration and the Non Methane concentration within a gaseous sample. The 109L is a table top or 19 inch rack mount Heated FID analyzer for the NMHC measurement in ambient air, exhaust gases from a combustion process e.g. stack emissions, from any type of an industrial vent, from an internal combustion engine, or from any other emission containing hydrocarbons. The 109L can be used as a table top or rack mount analyzer. It fully complies with EN 12619, EN 13526, QAL 1 (EU), with 2. BImSchV, 13. BImSchV and 17. BImSchV, (Germany) and with EPA Method 25A and Method 503 (USA).

The J.U.M. Engineering HFID Model 109L is a competitively priced, compact table top or 19' rack mount, heated Non Methane Hydrocarbon analyzer for the measurement in ambient air, air emissions and other gases.

With the exception of the sample filter, the 109L is 100% compatible with our successful long standing model 109A.

Two hydrogen flame ionization detectors (FID) are used in a heated oven to prevent the loss of high molecular weight hydrocarbons during measurement and to provide reliable performance in the analysis of both, low and high level concentrations.

All sample wetted components are integrated into the heated chamber. The heated sample filter is easily accessible via three screws on the rear panel. No special tools are required for the sample filter changes.

Low cost of ownership: Very low fuel gas consumption. The combustion air supply for the FID-detector is built in. No external cylinder for synthetic combustion air is needed.

The Flame Ionization Detection (FID) method is used to determine the presence of total hydrocarbon concentrations in a gaseous sample:

Burning  hydrocarbon-free  hydrogen  in  hydrocarbon-free  air  produces a negligible number of ions.

Once a sample  containing hydrocarbons is introduced into this flame a  very  complex  ionization  process  is  started.  This  process  creates  a large  number  ions.  A  high  polarizing  voltage  is  applied  between  the two   electrodes   around   the   burner   nozzle   and   produces   an electrostatic field. Now negative ions migrate to the collector electrode and  positive  ions  migrate  to  the  high  voltage  electrode.  The  so generated  ionization  current  between  the  two  electrodes  is  directly proportional  to  the  hydrocarbon  concentration  in  the  sample  that  is burned  by  the  flame.  This  signal  is  measured  and  amplified  by  our electrometer-unit.

One  of  the  two  sample  capillaries  is  connected  in  series  to  a  high temperature  catalyst  module.  This  catalyst  oxidizes  all  hydrocarbons except  the  methane.  Both  detectors  are  connected  to  individual electrometer  amplifiers.  From  these  two  signals,  total  hydrocarbons from  the  detector  without  the  catalyst  and  methane  only  from  the detector  with  the  catalyst,  the  non  methane  hydrocarbon  signal  is generated via a differential amplifier, resulting in the three continuous simultaneous signals displayed on individual digital meters.
