PRODUCT: VOC Acetaldehyde 1000μg.ml in Purge and Trap Methanol

PRODUCT No.: REVOC223

MATRIX: Methanol

DATE OF PREPARATION: 18th March 2020

EXPIRY DATE: 28th March 2023

PREPARATION OF STANDARD: All standard components have been pre-qualified/verified before use. All preparation has been performed in a cleanroom environment under strictly monitored and controlled conditions. All analytical measuring devices and instrumentation have been pre-calibrated. The actual concentrations reported below are based on this preparation methodology and compound impurities.

TRACEABILITY IN THE PRODUCTION OF THIS STANDARD: This product was prepared gravimetrically on a weight/volume basis. The solute was weighed on a balance calibrated by Reagecon engineers using OIML traceable weights. Reagecon holds ISO 17025 accreditation for calibration of non-automatic weighing machines (265C). The resulting Balance Certificate of Calibration was issued in accordance with the requirements of ISO/IEC 17025. The balance was calibrated under monitored environmental conditions and atmospheric pressure. Tests were performed for capacity, readability, repeatability, eccentricity and linearity. Dilution of the final product to volume was performed using internally calibrated Class A volumetric glassware.

BALANCE ID No.: RRD080 CALIBRATION DATE OF BALANCE: 11thMarch 2020

CALIBRATION AUTHORITY OF BALANCE: Reagecon Diagnostics Ltd, ISO17025 Accreditation No. 265C
