R t hr -R'+e where R'is the ionized species and he represents a photon which has an energy the ionization potential of the spetaes The sensor consists of a sealed ultra violet light source that emits photons which are energetic enough to ionize many trace species (particularly organics) but do not ionize the major components of air such as 02 N2,CO CO*. orH20, A chamber adja cent to the ultraviolet source contains a pair of electrodes When a positive poten tial is applied to one electrode the field created drives any ions formed by the absorption of UV light to the col lector electrode where the current (proportional to the concentration) is measured. Typical calibration curves showing the relative response of toluene and methyl ethyl ke tone (at the same gain setting) are shown below.

V photo-ionizer <1 n in i I stability Zero drift is extremely low normally 1% or less over 10 hours on battery operation. On AC operation, zero drift is less than 1 % over 24 hours Semiweekly span calibrations (100 ppm toluene) over a one month period give a relative standard deviation of 4 5%. This long term stability of both zero and span is due to the solid state electronics and stable ultraviolet light source. specificity Specificity in photoionization analysis depends on the sensitivity of the detector to the species being measured, the number of interfering species present, and the concentration of the species being measured relative to interferences. The optimum specificity can be obtained by choosing the light source (9.5 eV, 10.2 eV, 11.7 eV) to suit the application, maximizing sensitivity to the species being analyzed and minimizing any possible interference. Return the postcard for detai is on your application AC/DC operation-The instrument power is sup plied from a 12 VDC rechargeable batteiy which gives a minimum of 10 operating hours before recharging is necessary. The AC recharger pro vides the option of operating the unit continuously from 110V AC so that the instrument can be used either as a portable unit tor industrial hygiene sur veys and leak detection work or as a continuous stationary monitor An optional HNU Recorder can also be operated with the 101 battery The instrument is equipped with an automatic solid state battery protection circuit to prolong battery life by preventing deep discharging. Both the analyzer and the recorder can be operated during the recharge cycle. rapid response Response to changes in con centration is extremely rapid A 90% of full scale change (0-2000 ppm) takes less than five seconds In addition, the sensor is located at the sampling point rather than inside the instrument. This eliminates the problems of hydrocarbon adsorption and transit time through a sampling tube, all of which can delay the real time response by 30-45 seconds or more portability The instrument is truly portable, with a total weight of less than 9 pounds (4 1 Kg) com plete. No additional bulky power packs, sample pumps or cylinders of fuel gas or zero gas are needed. When not in use, the hand-held sensor is stored in the instrument cover and the total package measures 21 cm wide x 13 cm deep x 24 cm high.

The MEASUREMENT position allows the choice of a 0-2 ppm 0-20 ppm. 0-200 ppm or 0-2000 ppm full scale range The STANDBY mode reduces power consumption between measurements The BATTERY CHECK allows a manual power check before use while an t ED (red indicator light) adiacerit to the function switch provides an auto matic. battery check indicator during operation. Zero Adjust The zero control allows electronic calibration of the instrument at the zero concentra tion point without requiring the use of a zero gas Span To calibrate the instrument fora particular gas. this control is adjusted to the gain setting which will match the value of u calibration gas to that same read ing on the instrument scale This control also provides the 10 fold increase in gain that allows the 0-2 ppm full scale range recorder outputs A signal output of 0--5V full scale is provided on the front panel for the attachment of a strip chart re corder. electronic zero Zero calibration is done com pletely electronically The instrument is switched to the STANDBY mode where the UV light source is turned off but the other electronics remain on The zero control is adjusted until the meter indi cation is zero No zero gas or regulators are needed, no further adjustments are required Verification tests for this technique against hydrocarbon-free zero gas show perfect agreement safety The photo-ionizer is extremely safe to use. requiring no flames, igniters, or hydrogen fuel It is approved by FM to meet the safety requirements of Class 1.
