| Problem, Need or Value | CleanAir's System | What To Look For | Bias Error or Result | Possible Outcome | |
|---|---|---|---|---|---|
| Dissolved probe or nozzle material contaminating sample. | Eliminate sources of probe and nozzle contamination. | Green tint to probe wash beaker. Also, for metals test look for probe parts containing metals of interest in contact with the sample or wash. | Positive particulate and metal emission bias could result in a reported emission many time actual emissions. Error always penalizes source operator | Failed Compliance, NOV, Retest, Fail Guarantee, Unneccassary APC Capital expendature. Bad PR . Reduce production or close plant. | |
| Gas flow measurement bias for S-Type Pitot. | Geometrically accurate pitot for every test. | Pitot tip with burrs or misalignment | Up to + 15% total gas flow error. Error generally penalizes source operator. | Increased reported total pounds per hour emissions by up to 15%. Buy more or sell fewer emission credits, reduce production. | |
| Accurate measurement of turbulent flow. | Cyclonic flow determination on every stack and use 3D flow probe based on value determination process. | Cyclonic flow check data sheet in report. | up to + 25% total gas flow error. Error generally penalizes source operator. | Increased reported total pounds per hour emissions by up to 15%. Buy more or sell fewer emission credits, reduce production. | |
| Analytical instruments shipped from job to job without checkup or cleaning. | Bench check instruments after each job with the instrument technicians card attached to the top. | Ask to see the instrument log repair history file and bench calibration. | Error should be identified with field calibration. | Testing delayed by bad calibration. | |
| Heated sample lines shipped from job to job without checkup or cleaning | Flush HSL after each job then use CO and THC analyzers to confirm that the residual levels are less then 1 ppm. | HSL shipping box label. HSL maintenance history file and cleaning test chart. | Error should be identified with field zero calibration. | Testing delayed by high bais. | |
| Variation caused by field contamination. | Pretest field blank for every test, even if not required by the test method. | Extra sample train a the test location with full setup and recovery. | Test results can be unknowingly baised high. | Failed test. Testing may have to be repeated. | |
| Contamination of sample during probe insertion or removal. | CleanAir has a defined system for ensuring port cleanlyness. | Ask to see the probe isible | |||
| Test port air in-leakage contamination. | CleanAir has a defined system for sealing ports. | Gloves or rags stuffed in ports where the gas static pressure is negative. Also look for low gas temperature at the points near ports | Gas temperature, gas flow and concentration could be baised low or high. | Hard to quantify economic impact of this bad test data. | |
| Contaminated blanks. | Instrument grade reagents and new glassware for every reagent preparation. | Lab and field blanks that are more than the sample. | |||
| Negative sample weights. | We pre-condition filters before use and select the filter media will not be attacked by the compounds present in the sample gas. | Negative sample weights. | |||
| Field delays and problems caused by test equipment failure. | Rugged and dependable test equipment. Is it engineered to eliminate failure? Is it well maintained? | Equipment failure contingency plan. | Possible bias error but bigger concern should be fabrication to replace lost data. | Delayed testing. Prolonged process operation at test condition, such as reduced load,could be very costly. | |
| Lost of computer stored test data. | Back-up all project-related computer files on a DAILY basis in field and office. | Field computer backup disk which is stored off site. Ask to see office backup system. | No bias error unless data is fabricated to replace lost data. | Repeat of testing program may be needed but may not be possible in special situations. | |

| Safety first | Safe work habits. | Safety is Cleanair's highest priority! Our aim is zero safety incidents. | NA | An accidents can cause major problems. We work to eliminate this possibility. | |
| Dry gas meter calibration drift to unacceptable value. | Field monitoring of dry gas meter’s performance on an on-going basis. | ||||
