  Properties:
Aldosterone (CAS No. 52-39-1) 31.2 ± 4.6 (pg/mL)
Cortisol (CAS No. 50-23-7) 94.4 ± 8.1 (ng/mL)
Testosterone (CAS No. 58-22-0) 4.65 ± 0.52 (ng/mL)

Remarks:
The form of this CRM is yellow liquid at room temperature. Approximately 0.5 mL of material was bottled in the plastic vial, and the vial was kept in an aluminum-laminated bag. This CRM should be kept under -80 °C and protected from light.

Intended Use:
This CRM is intended primarily for use in calibration of analytical instrument and evaluating the accuracy and validation of analytical procedures or instruments for the determination of aldosterone, cortisol and testosterone in human serum by instrumental analysis.

Remarks:
Environment and Climate Change Canada matrix reference materials (RMs) are collected in bulk from various locations across North America. LETH-13 was collected from Lethbridge, Alberta in 2013. The bulk sample was pre filtered to remove particulates and filtered through a 0.2 µm sterilizing filter to remove bacteria. This bulk Major Ions and Nutrients in water RM is stored in a dark cold room and is unpreserved.

Intended Use:
This Reference Material is intended for the verification or development of analytical methods for environmental analysis. It is not intended for use as a calibration standard.

Remarks:
Environment and Climate Change Canada matrix reference materials (RMs) are collected in bulk from various locations across North America. LON-18 was collected from Lake Ontario in 2018. The bulk sample was pre filtered to remove particulates and filtered through a 0.2 µm sterilizing filter to remove bacteria. This bulk Major Ions and Nutrients in water RM is stored in a dark cold room and is unpreserved.

Intended Use:
This Reference Material is intended for the verification or development of analytical methods for environmental analysis. It is not intended for use as a calibration standard.
