O GASERA FTIR accessory PAIO Photoacoustic gas analysis module Pirlo PHOTOACOUSTIC Db Et eee eR Sensitivity and low volume The PAIO measures low concentrations from very low gas volumes High sensitivity is obtained by utilizing the patented cantilever based optical microphone technology PA signal Linearity The photoacoustic signal unlike the conven tional infrared detector output is highly lin ear in a very wide dynamic range because 3200 ME _ 2850 new photoacoustic technology allows the use of short absorption path length without losing Infrared spectrum of the 3000 cm band of 100 sensitivity Wide linearity range allows the effi PPM methane measured from 10 ml gas vol cient subtraction of unwanted signals such as ume 2 cm resolution 100 scans with 2 5 kHz water Generally water vapor occurs in much FTIR mirror speed higher amounts in gas mixtures than the analyte gas and it is usually very difficult to subtract us ing conventional detection NO x10 offset Sample NO Reliable concentration monitoring Absorption is measured directly with pho POETA toacoustic technique This makes the measure ment free of drift It is the key factor for the unbeatable stability and reliability without frequent background measurement Unlike in conventional transmission technique interfer ometer instabilities do not show as large drifts in the photoacoustic
3. acoustic background Total gas volume of the system is low approx 30 ml A simple user interface with a display and buttons The gas exchange procedure is user configurable The gas exchange can be started manually with a press of a button or the instrument can be programmed to do it automatically using timer or an external trigger Three gas connections in the front The sample gas has two connections one for input and one for output The input is equipped with a particle filter The purge input is for the IR beam path purging Temperature stabilized gold coated gas cell with user select able temperature from room temp to 50 C Patented ultra sensitive optical microphone based on a MEMS cantilever sensor coupled with a laser interferom eter to measure microscopic movement of the cantilever sensor Complies with the following standards or other stan dardization documents under the Low Voltage Directive 2006 95 EC and EMC Directive 2004 108 EC EN 61326 1 2005 EN 61010 1 2001 12 months warranty Technical specifications Materials in contact with gas FPM FKM o ring seals solenoid valve seals PS EPDM gas pump Resin solenoid valves Stainless steel solenoid valves tube connectors IR window BaF2 KBr etc Readout window SiO2 Nickel gas exchange unit block tube connector PTFE tubes particle filters PP particle filters Dimensions 16 5 cm W x 29 0 cm H x 16 5 cm D 6 5 inW x 11 4 in H x 6 5 in D
