Ethanol Testing by ASTM Standards

Project Description

I am interested in working with you on a quote for analytical testing on a sample of ethanol from our plant. The sample is >98% ethanol, with <1% water. There are a few criteria that we would like itemized in the quote:
1. Include analysis for the components in the list below
2. Provide a named analytical procedure for each analysis. These can be in-house methods for the components labeled Standard must be provided by testing lab.
3. Results should be provided in ppm.
4. Results may be reported as < if a defined number can't be estimated with accuracy.
5. Results should be reported with uncertainties (I would expect analysis to be performed in triplicate?)

Here is the component list:

Number Component Proposed Testing Standard
1 2-butanol Must be provided by Analytics Lab
2 1-propanol Must be provided by Analytics Lab
3 2-methylpropanol Must be provided by Analytics Lab
4 3-methyl-1-butanol Must be provided by Analytics Lab
5 Acetaldehyde Must be provided by Analytics Lab
6 Esters (ethyl acetate) Must be provided by Analytics Lab
7 Oxygen Must be provided by Analytics Lab
8 Total nitrogen compounds as N ASTM D7184-20
9 Acetonitrile as N Must be provided by Analytics Lab
10 Total sulfur ASTM D5453 or ASTM D7184-20
11 Total cations (Zn, Cu, Fe, Na, Ca) ICP-AES (ASTM D1688 for Cu)
12 Phosphates ASTM D3231 (phosphates)
13 Benzene ASTM D3606
14 Total aldehydes Must be provided by Analytics Lab
15 Dry extract ASTM D381

Please reach out with questions.

Thanks.
