Invitation to Bid – Dry Gas Ethanol Reference Material and Certified Reference Material for Breath Alcohol Testing Devices

Page 1 of 2 Rev. 06092026

All qualified suppliers wishing to submit a response to this Invitation to Bid (ITB) must be able to provide the Alabama Department of Forensic Sciences (ADFS) with dry gas ethanol reference material (RM) and certified reference material (CRM) for use in the evaluation and calibration of breath alcohol testing devices.

I. MINIMUM REQUIREMENTS

1) The dry gas ethanol RM and CRM manufacturer must be an ISO 17034-accredited Reference Material

Producer. The supplier must provide a copy of the manufacturer’s accreditation certificate with their response.

2) The supplier must agree to accept the empty RM and CRM cylinders and provide the necessary shipping materials for return at no cost, including return shipping costs.

3) The supplier must be able to invoice ADFS based on the order.

Dry Gas Ethanol RM Specifications

4) The supplier must supply dry gas ethanol RMs for the following concentrations:

a. 0.020 g/210 L

b. 0.040 g/210 L

c. 0.080 g/210 L

d. 0.100 g/210 L

e. 0.150 g/210 L

5) The concentration of each dry gas ethanol RM must be within ± 2 % or 0.002 g/210 L, whichever is greater than the stated concentration for the entire life of the standard.

6) The dry gas ethanol RMs must be blended ethanol in nitrogen gas for use with a breath alcohol testing device.

7) The dry gas ethanol RM cylinders must be aluminum, refillable cylinders designed to contain a minimum of

108 liters of gas at 1200 psi at 70º F.

a. Only proposals that specify aluminum, refillable cylinders will be considered

8) Each dry gas ethanol RM cylinder must bear a label displaying the following information at a minimum:

a. Concentration of standard expressed in g/210 L when delivered into a breath testing device at sea level

b. Lot number and tank number within the lot

c. Manufacture date

d. Expiration date

e. Identity of the preparer

f. Supplier name and address

9) Dry gas ethanol RMs must be directly traceable to NIST (National Institute of Standards and Technology), NTRM (NIST Traceable Reference Material), CRM (Certified Reference Material), RGM (Research Gas Mixture), or SRM (Standard Reference Material) calibration gases.

10) The supplier or manufacturer must provide a Certificate of Analysis with NIST Standard information and all necessary data to ensure uncertainty calculations can be accomplished. The Certificates of Analysis for each individual cylinder must be available online.

11) The supplier must replace any dry gas ethanol RM found to be contaminated or failing to meet the acceptable criteria for any concentration described in Item 4 at no cost, including delivery and return shipping costs.

12) The supplier must guarantee the refill and return of RM cylinders within three weeks of receipt.

13) To monitor stability, the supplier must have a system for retaining and periodically re-analyzing cylinders from every passivation lot. The stability data must extend back for at least 4-years and must be for the same cylinder material and valve components to be supplied.

Dry Gas Ethanol CRM Specifications

14) The supplier must supply dry gas ethanol CRMs in 150 cu. ft. cylinders for the following concentrations:

a. 0.020 g/210 L

b. 0.080 g/210 L

c. 0.150 g/210 L

15) Each dry gas ethanol CRM cylinder must bear a label displaying the following information at a minimum:

a. Concentration of standard expressed in g/210 L when delivered into a breath testing device at sea level

b. Lot number and tank number within the lot

c. Manufacture date

d. Expiration date

e. Identity of the preparer

f. Uncertainty

g. Supplier name and address

16) Dry gas ethanol CRMs must be directly traceable to NIST Traceable Reference Materials (NTRMs), Research Gas Mixtures (RGMs), or Standard Reference Materials (SRMs) calibration gases.

17) The supplier or manufacturer must provide all necessary data collected during the manufacture and verification of the dry gas ethanol CRMs (150 cu. ft.) to ensure uncertainty calculations can be accomplished.
