About this file
This document is an Attachment B specification for a Volatile Organic Compounds (VOC) Internal Standard purchase for the Texas Commission on Environmental Quality (TCEQ), detailing requirements for a specialized gas standard to be used in canister analysis by EPA method TO-15. The specification requires a gas standard with six specific internal standard compounds, each at precise concentration levels (ranging from 10-20 parts per billion by volume), to be delivered in a spun aluminum cylinder with at least 4000 liters of product, a minimum cylinder pressure of 2000 psig, and an expiration date no less than one year from the requested delivery date.
The vendor must have ISO 9000 or higher certification, provide a certificate of analysis with ±10% accuracy and blend tolerance, and ensure the standard is NIST traceable by weight. The standard will be balanced with Ultra High Purity nitrogen gas and must be free of a comprehensive list of potentially interfering compounds. TCEQ will inspect and analyze the standards within 30 calendar days of receipt, and payment will be made within 30 days after the standards are found to meet specifications or 30 days from invoice receipt, whichever is later. The document includes detailed tables listing the required compounds, their Chemical Abstracts Service (CAS) numbers, and concentration requirements.

ATTACHMENT B
Specifications for TO-15 Internal Standard (6 Compounds) Purchase For use by the Texas Commission on Environmental Quality (TCEQ)
12100 Park 35 Circle, Bldg. B, Austin, TX 78753
Description: This internal standard will be used for TCEQ Volatile Organic Compounds (VOC) Canister analysis by EPA method TO-15.
MINIMUM GENERAL SPECIFICATIONS
1) Item must be analyzed and arrive with a certificate of analysis with a minimum of
±10 % accuracy and a blend tolerance of ±10%. Standards must be National Institute of Standards and Technology (NIST) traceable by weight. The standard will have a balance of Ultra High Purity (UHP) nitrogen gas.
2) The name of each compound, the Chemical Abstracts Service (CAS) number, and concentration in parts per billion by volume (ppbv) must be listed on the certificate of analysis.
3) The standard must have at least 4000 liters (L) of product and a minimum cylinder pressure of 2000 pounds per square inch gauge (psig). The cylinder must be of spun aluminum construction with internal passivation to deter chemical component interaction or degradation and must have a Compressed Gas Association (CGA) 350 fitting.
4) The standard cylinder must not have an expiration date of less than 1 year from the requested delivery date. An expiration date must be printed on the certificate of analysis.
5) The facility must have a registered ISO 9000, or above, certification. In addition, the vendor’s production laboratory, which will blend the standard, must have an International Organization for Standardization (ISO) 9000, or above, certification, and must be able to supply certification re-verification to the TCEQ upon request.
7) Delivery must be made after receipt of order to TCEQ, MC 165, 12100 Park 35 Circle, Building B, Austin, Texas 78753.
8) The gas standards shall be inspected and analyzed within 30 calendar days of receipt by TCEQ and must agree with reference standards within 10% before deemed acceptable. Payment will be made within thirty (30) calendar days after the standards are found to meet specifications, or 30 days from the date the invoice was received, whichever is later.

9) Analyte list for the 6 internal standard compounds, CAS number, and concentration in parts per billion by volume (ppbv) must be:
Compound CAS# Concentration
(ppbv) 1,1-dichloro-1-fluoroethane 1717-00-6 10 chlorobenzene-D5 D5(108-90-7) 10 1,4-diflurobenzene 540-36-3 10 D6-benzene 1076-43-3 10 1-bromo-4-flurobenzene 460-00-4 20 2-bromo-1,1,1-trifluroethane 421-06-7 10
10) Any compound on the list below that is detected above 0.05 ppbv will result in the standard being rejected by TCEQ. The standard should be made with new cylinders or with the cylinders previously used for the same components.
Compound CAS No.
