Anthraquinone Analysis Offered by Columbia Analytical

Wednesday, July 23rd, 2008

The GC-MS is used for testing anthraquinoneColumbia Analytical has completed the implementation of the National Council of Air and Stream Improvement (NCASI) Method AQ-S108.01 for the determination of anthraquinone in pulp and paper products.

In response to California’s listing of anthraquinone with Proposition 65, many companies are proactively having their products tested for anthraquinone in advance of the ruling’s effective date. This procedure is currently being performed by Columbia Analytical as written and released by NCASI.

Columbia Analytical has been in consultation with NCASI scientists over the past year in preparation for this action by the state. This preparation enabled Columbia Analytical to be in position to offer the Gas Chromatography/Mass Spectrometry (GC/MS) procedure in time for pulp and paper operations to comply with the regulation.

Columbia Analytical is currently analyzing for anthraquinone in samples for multiple organizations.

NCASI Method 99.02 Testing at Columbia Analytical

Sunday, July 4th, 2004

In support of MACT standards, CAS has been working with the National Council of Air and Stream Improvement (NCASI) to bring NCASI Method 99.02 (Impinger/Canister Source Sample Method for Selected Compounds at Wood Products Facilities) on line. The procedure calls for a number of changes that will require careful communication between the source testers and laboratory personnel. Since the method is intended to be prescriptive, no modifications are allowed. Thus, CAS is bringing the laboratory portion of the procedure on line without modification.

Our laboratory in Simi Valley will be performing the canister portion of the procedure (i.e. gas analysis). The analysis is performed using gas chromatography/mass spectrometry (GC/MS). The target compound list will generally consist of Methanol, Acetaldehyde, Acrolein, Phenol, and Propionaldehyde. In addition, Benzene will be required for many applications. The laboratory will also have the capability to analyze for the full suite of compounds included in Method 99.02.

Our Kelso laboratory is doing the aqueous impinger work, which includes Methanol, Acetaldehyde, Acrolein, Phenol, and Propionaldehyde by gas chromatography/flame ionization detection (GC/FID) fitted with a chilled autosampler. Formaldehyde is analyzed using a colorimetric procedure.

Simi Valley will prepare a spiked canister and ship it to the field with the other canisters. Kelso will prepare the field spike solutions for the impingers, as well as the internal standard spike solution. Note that two spike concentrations will be recommended in order to comply with the procedure because of the risk of not correctly predicting the appropriate concentrations of the source. Since the method allows for an alternative approach of preparing a high level and low level matrix spike, this probably will be the preferred practice for the impinger samples to avoid out of compliance matrix spike results. A single spike will be done for the gas sampling.
