8 PROCUREMENT, INVENTORY & TRACEABILITY OF SUPPLIES
8.1 Procurement / Inventory
All consumable supplies are purchased from reputable vendors that have been evaluated for service, quality, ,
and price. To the extent possible, materials traceable to national or international standards of measurement are
purchased for use in technical operations. Supplies are purchased using ACZ's purchase order (PO) and
inventory system database. The Purchasing Agent is not permitted to make a substitution for any material(s)
specifically requested unless the department supervisor approves the substitution. Upon receipt, reagents, _
chemicals, standards, and other laboratory consumables are stored in the Chemical & Supply Room, which has
limited access, or are delivered to the laboratory. Refer to ACZ's SOP Purchase, Receipt, and Storage of
Consumable Materials for Technical Operations (SOPAD037) for additional information.
8.2 Glassware
ACZ uses only laboratory grade glassware. Prior to use, glassware is cleaned using Alconoxo or Chemsolveo (or i
other appropriate detergent) and then rinsed with Type I water. Glassware for trace metals is subsequently rinsed
with 50% Nitric Acid and rinse again with Type I water. Glassware for nutrients is subsequently rinsed with 10% ,
Hydrochloric Acid and then with Type I water. All glassware for organic analyses is washed with Alconoxo then
rinsed with de-ionized water and kiln-baked. Glassware for radiochemistry analyses is washed first with
Contrad700 and then with 50% Nitric Acid and is rinsed with Type I water. Clean glassware must be stored in an ,
enclosed cabinet or other suitable container and/or covered with Parafilm or foil.
8.3 Other Supplies
Routine consumables (centrifuge tubes, autosampler tubes, pipette tips, etc.) are purchased through an automatic ,
system managed by Fisher (RIMS). All other supplies are purchased on an as-needed basis through ACZ's
Purchase Order and inventory system database. Refer to SOPAD037 for additional information.
8.4 Traceability of Standards and Reagents
To provide complete traceability, each data package must reference every standard and reagent used for sample

preparation or analysis, including but not limited to acids, bases, preservatives, color reagents, pH indicators, '
buffers, instrument reagents. Each PCN and/or SCN must be documented either on the workgroup bench sheet,
data review checklist, or a current standard/reagent form. The open date for all original containers is not tracked in

8.4.1 Primary Control Number (PCN)
Upon receipt, all stock chemicals, standards, and reagents are assigned a unique PCN in LIMS for
tracking and traceability purposes. A label with the PCN and the expiration date is affixed to both the
container and the Certificate of Analysis (if applicable). Document Control enters the data for each
PCN using the certified value(s) supplied by the vendor, as indicated on the Certificate of Analysis.
Because the certified value is entered, the final concentrations for prepared standards may vary
slightly from the theoretical value indicated in the test SOP. Non-certified values are not entered and
are not used for quality control purposes. Document Control maintains certificates of Analysis, and a ,
copy of the PCN report is generated and maintained. If data for any PCN is to be edited, then
complete documentation must be provided as a major corrective action (FRMQA001).
NOTE: Only Document Control and QA/QC personnel are authorized to enter or edit PCN data.
