Clean Air Engineering’s organic laboratory specializes in the analysis of samples collected from source and ambient test programs. CleanAir uses gas chromatographs manufactured by Hewlett Packard, Perkin Elmer and MTI coupled with flame ionization, flame photometric and thermal conductivity detectors. CleanAir requests that all sample analysis be confirmed verbally before sending samples to verify that the analysis is within our capabilities. The price schedule for organic analysis per sample is as follows:

First Compound Each Additional Compound

Adsorbent Tube $145/sample $65/sample

Impinger Catch $145/sample $65/sample

Tedlar Bag $145/sample $65/sample

Coating and Ink Analysis

EPA Method 24 $425/sample

Clean Air Engineering’s organic laboratory regularly performs EPA Method 204f distillations on liquid coating and ink samples. Using a Roto-Vap, a liquid sample is generated that can be used to determine response factors for total hydrocarbon analyzers.

EPA Method 204f ..... $155/sample

Ten or More Samples ..... 10% Discount on Analysis

Twenty or More Samples ..... 25% Discount on Analysis

Inorganic Analysis

Clean Air Engineering’s inorganic laboratory utilizes a Dionex Model DX2000i ion chromatograph. All analyses are performed in accordance with procedures in US EPA Methodology. Full pre and post analyses calibrations are provided as part of the per project pricing. The price schedule for inorganic analysis is as follows:

Ion Chromatography - Cations

Lithium: $54/sample

Gravimetric Analysis

Clean Air Engineering’s gravimetric laboratory performs analysis on particulate samples collected using federal and state test methods.

Gravimetrics - Method 5, Method 17, CARB Method 5

Front-Half Analysis

Filter^¹: $18/sample

Probe Wash: $39/sample

Back-Half Condensable

Gravimetric analysis of aqueous condensable (inorganic): $39/sample

Separate pressure filtration analysis: $45/sample

Please note that some states may require the additional back half filtration. If Method 202 sulfate analysis is required, ion chromatography charges will apply (see page 2).

The separate pressure filtration analysis would be required for EPA OTM-028 filter extracts if fiber filters are used instead of membranes for the ambient filter.

Laboratory Resistivity Determinations

Laboratory resistivity and particle size analysis of particulate can be determined to aid in improving control device performance. CAE determines resistivity as a function of temperature in accordance with IEEE Standard 548. Particle size is determined using the Bahco Micro Particle Classifier.

IEEE Standard 548-1984

Round Trip - Resistivity measured as a function of ascending and descending test temperature between 85°C and 450°C in an environment of air containing one specified water concentration at an average electric field intensity of 4kV/cm $1,175/Sample

Ascending temperatures only; otherwise same as round trip: $925/Sample

Descending temperatures only; otherwise same as round trip: $795/Sample

Descending temperatures with one ascending data point at the temperature of principal interest; otherwise same as round trip: $875/Sample

Resistivity as a function of applied electric field at a specified
temperature: $795/Sample

With Sulfuric Acid or Ammonia Environment; EPA Report 600/7-78-035

Single point determination - Resistivity measured isothermally as a function of electric field intensity in an environment of air containing a specified concentration of water and sulfuric acid or ammonia vapor (48 hour test) $1,175/Sample

Each additional data point produced by changing temperature, water concentration, sulfuric acid vapor concentration or ammonia vapor concentration (24 hour test): $795/Sample

Computer Model Resistivity Predictions

Resistivity predicted as a function of temperature and environmental conditions (water and sulfuric acid concentration) using customer-supplied coal and ash compositional data. Model II described in EPA-600/7-86-010 is used; with brief comment $275/sample

Predicted inherent and sodium-depleted volume resistivity using customer-supplied ash compositional data. Described in EPRI Report CS-3421; with brief comment: $275/sample

Computer Model ESP Performance Predictions

Particle collection performance of an electrostatic precipitator is predicted using customer-supplied precipitator mechanical and electrical data as well as coal and fly ash compositional data. Model is described in EPA-600/7-84-069 a&b and is commonly referred to as the EPA/SRI computer model. In addition to modeling the existing precipitator performance, the effects of various changes (such as coal switching and gas conditioning) can be predicted. Priced according to scope and complexity.

Other Services

Scanning electron microscopy (SEM), x-ray diffraction, designed resistivity tests, and consultation work are available and are priced according to scope and complexity.

Rush Analysis Pricing

Analytical results will be issued 15 working days from the receipt of samples. Rush analytical results may be available at increased rates upon request. Rush charges for analysis will be applied in the following manner:

1-2 working days 300% of set price

3-5 working days 200% of set price

6-10 working days 150% of set price

In any circumstance, a purchaser’s request for rush analysis in a certain time frame authorizes all degrees of rush charges up to that extent. Rush charges on the final invoice will be reflective of when results were available and reported to the Purchaser. All days will be calculated on a five (5) day work week (except for holiday allowance).

All analysis will be performed according to Clean Air Engineering’s
Terms and Conditions for Laboratory Work.

1 Pricing for post-test analysis only. Tared filter media are priced separately.
