Heated Sample Handling Instruments and Acessories

The VE 112 is an efficient, all heated, low pressure drop sample filter and interface for removing solids from a gaseous sample and supplying sample to up to 5 gas analyzers. It utilizes a permanent all stainless steel 2 micron mesh filter and all stainless steel valve in a thermostatically controlled oven to prevent the loss of high molecular weight hydrocarbons or condensation of water. The sample filter is to be cleaned by high pressure pack purge with compressed air or nitrogen.

The Model VE 112 can be installed in the instrument rack as a complete sample interface for all relevant gas analyzers. With its filter back purge system it offers up times at comparatively low maintenance time and cost. The sample probe and sample line are both automatically cleaned from dust and condensed hydrocarbons which every filter back purge cycle. In most cases, a stack probe filter is no longer needed.

A calibration gas inlet offers the capability to test and calibrate the complete sample train and analyzer circuit. Our proprietary rear panel adapter plate system allows cold-spot free coupling of a heated sample line inside the heated oven without the need of special tools.

The Model VE 222 is an efficient, all heated and low pressure drop 2-stream sample sequencer, filter and interface for removing solids from two gaseous sample streams. The Model VE 222 utilizes two independent permanently installed all stainless steel mesh sample filters and two independent all stainless steel sample valves in a thermostatic controlled oven to prevent the loss of high molecular weight hydrocarbons or condensation of water.

The permanent sample filters are regenerated in a matter of seconds by back purging them with high pressure air or nitrogen

The VE 112WP is the wall or panel mount version of our time proven VE112 heated sample filter and interface. Can be mounted in a separate NEMA 4 type housing or the system with all analyzers and sample cooler. With our unique sample back purge system, typically no sample filter at the stack probe is needed. During back purge not only the internal sample filter is cleaned, but also the heated sample line between the stack probe and the CEM is rigorously cleaned and freed up from condensing matter and hang up. Such guarantees extended working up times at comparatively low maintenance cost.

The Model 108 dilutes an introduced sample gas in a 1:10 (standard), or a 1:100 (optional) dilution rate to allow the linear measurement of hydrocarbon concentrations above several thousand ppm up to 10% and above. The sample injection method is used in this 190 deg.C heated sample diluter for fast response and improved zero and span stability of a hydrocarbon measurements.

The Model 108 is also used to minimize negative effects due to highly concentrated interference compounds and contamination. Additionally, so called "memory effects" or hydrocarbon hang-up due to condensation of heavy hydrocarbons as well as other condensed impurities in the sample gas can be largely prevented.

A total hydrocarbon analyzer, placed downstream of the diluter will continuously draw a constant amount of zero or room air through the diluter.

The internal sample pump draws the sample into the diluter. The Model 108 is equipped with a permanent sample filter to be back purged with high pressure air or nitrogen for cleaning, 2 micron stainless steel sample filter. Downstream of the internal sample pump is the actual dilution capillary setup which is controlled by precision flow/pressure regulation to ensure a constant flow of sample through the diluter capillary. The diluter capillary flow is finely adjustable to maintain the correct injection amount.

Features

• All components in contact with sample fully heated and accurately controlled at 190 deg.C

• Built-In air pressure pump and heated sample pump

• 1:10 dilution rate is standard

• 1.100 dilution rate is available instead of 1:10 as an option

• Standard, permanent installed sample filter to be cleaned by back purge with hydrocarbon free compressed air or with nitrogen.
