Superior work is always acceptable. Yes, to the isotope dilution high-res procedure.

Thank you, Peter. 

 

It is also understood that we can use a superior methodology to 8270; i.e., isotopedilution high-resolution gas chromatography and high-resolution mass spectrometry (e.g., 

CARB-429 HRMS version) because it offers better detection limits as well as higher data 

quality. I am referring to the figure below, which was discussed at PCB last March.

Yves: 

 

1 and 2) We asked the project lead to develop a list of compounds of 

interest for the particular program so that we could define the method 

(s) accordingly and reduce at least some of the confusing issues we had 

with the utility MACT sampling and analysis requirements. The answer is 

that list of PAHs. We will certainly accept data for other compounds in 

addition to those listed if analyst wishes to provide those. 

 

3) Yes, the laboratory may combine the three fractions extracted as per 

Method 3542 and analyze them as one using Method 8270C or D as you have 

outlined.

Dear Robin, 

 

Thank you for returning my call last Friday. I actually missed your call 

by a few picoseconds. 

 

 1. The list of PAHs (see attachment) contains 16 PAHs (most likely 

 derived from 8270 rather than CARB-429). In any case, our approach 

 covers those 16 PAHs plus three additional ones. 

 

 2. The attachment mentions 8270 C and D without mentioning the SVOST 

 compounds typically covered by 8270. Thus, I assume PAHs are the 

 only target analytes from 8270 (or equivalent CARB-429) that the 
4

 ICR is after. 

 

 3. The attachment does mention 3542, which means that the three 

 fractions (FH, BH and Impinger) are prepared and analyzed 

 separately leading to three analytical runs. This is the same 

 issue we discussed at length at PCB last March and ended resolving 

 by allowing the three fractions to be analyzed as a single sample 

 so long the lab was able to monitor the extraction efficiencies of 

 the impinger fraction (extracted as a water; i.e., different than 

 the solid phase that is done by Soxhlet Dean-Stark for the FH/BH) 

 independently from the solid phase extraction. Thus, I assume that 

 the same thinking would apply for this ICR. But I would prefer to 

 check with you before contacting the client who requested a quote 

 from us. 

 

To summarize (limited to SVOST): 

 

 a) One train per run is collected for the PAHs. 

 b) The list of 19 PAHs (CARB-429) is acceptable since it 

 includes the 16 PAHs listed in the ICR. No other SVOST analytes 

 are required. 

 c) The three fractions (FH, BH, and Impinger) can be 

 processed so that only one analytical run per train is performed 

 provided the lab monitors and documents the extraction 

 efficiencies for both aqueous and solid phase’s extractions. 

 

Please let me know if this translation meets your expectations. 

 

Cheers, 

 

Yves
