14. Dual Detectors Dual Detectors 1 6 TVA2020 Instruction Manual The benefits of each individual detector are very clear both the FID and the PID have their advantages and disadvantages However with either detector alone the number of organic and inorganic vapors that one can detect is limited by the measurement capabilities of that detector With the TVA2020 users can obtain more complete information about organic and inorganic vapors more quickly and easily than with single detector technology alone Since both detectors may be displayed and logged simultaneously the relative response of the two detectors may give some clues about the identity of the compound being measured see Figure 1 3 For instance the PID does not respond to methane at all but the FID responds very well A high FID reading with virtually no PID response might indicate the presence of methane Consequently PIDs respond very well to some inorganic gases that FIDs cannot detect A high PID reading with no FID reading might suggest the presence of an inorganic compound With readings from both detectors readily available the TVA2020 can help a user make decisions about the type of compound present and which detector reading to use Thermo Fisher Scientific Introduction Dual Detectors PID 00000 PPM FID 00000 PPM AMPLIFIER METER EXHAUST FLAME ARRESTOR a TVA2020 COLLECTOR ELECTRODE IGNITION FILAMENT COLLECTOR ELECT

27. To maximize standard accuracy it is highly recommended that you calibrate with methane for the flame ionization detector and isobutylene for the photoionization detector Almost all published response factors for FIDs and PIDs are based upon methane and isobutylene respectively By employing a multipoint calibration for these compounds you will improve the accuracy of each detector over the entire dynamic range Response factors curves can then be employed for correcting the detector s response to different compounds However once a multipoint calibration has been employed any response curve must characterize only the relative response at each concentration excluding curvature of the calibrated compound Thus use of both multipoint calibration and response curves at the same time is difficult and is not recommended If for example you want to measure several different compounds over wide concentration ranges it is best to use a single point calibration and then enter response curves for each specific compound up to 9 response factors curves can be entered into the analyzer TVA2020 Instruction Manual 4 1 Calibration Calibration Scenarios Scenario 3 4 2 TVA2020 Instruction Manual A If instead you want to measure in direct readings response factor 1 for one specific compound with maximum accuracy over a wide range of concentrations perform a multipoint calibration with the specific compound Up to 9 span points plus
