PRINCIPLE

All glass purging device is designed to accept 5 ml samples with water column at least 5 cm deep. Dead volume must be less than 15 ml. We need inert gas to purge 5 ml water sparger with bubbles (created by the frit) less than 3 mm at the base of the sample . N2 generator is delivered with this automatic sparger.

Automatic water rinsing for surveillance with liquid pump and injection system for 5 ml

NITROGEN

N2 generator: N2 production contains less than: 2 ppm O2 10 ppt Total Hydrocarbon Dew point < -18°C

N2 flow regulation for VOCs extraction: 40ml/min Volume calculation is memorized in VISTACHROM Unit display can be mass (ng) or µg/L

PURGE & TRAP WITH VALIDATION

11 minutes purge & trap extraction for: Range = 0.01 to 200 μg per liter (water) or m3 (air).

airmoCAL is used for: VOCs Linearity Zero validation with blank Calibration / Inter calibration by liquid and gas airmoCAL D in option for cylinder dilution

Air analysis above surface water in sequence with water analysis for validation of results and water quality control with airmozone Purge & Trap

DISPLAY SOFTWARE & DATA TRANSFER

VISTACHROM display: Pressure, flow, temperatures on the

supervisor Purge sampling temperature Communicate sampling / analytical / calcul

parameters to final end user.

For traceability Chromatotec use a supervisor

CONCLUSION

All our competence and experience on air quality monitoring (European Certifications, US EPA Test, Chinese National Certification…) allow us to develop water quality monitoring.

The calibration is in gas and we compare it to a calibration in water which is not much stable.

We can supply various detectors, a FID (reference detector: linear and stable) and other detectors : PID and ELCD (502.2 method), Mass Detector (524 method).
