Cobalt-Nickel-Nitrate Solutions

STRANASKA® CRM 200
This reference material artifact is intended for the calibration and/or verification of the absorbance scales of molecular absorption spectrophotometers in the ultraviolet (UV) and visible (VIS) regions of the electromagnetic spectrum. Derived from the NIST SRM 931 series, it is comprised of three solution/cuvette filters which are provided in a protective canister for storage and transportation purposes. Each solution/cuvette filter is individually calibrated, relative to an air-only reference path, for apparent absorbance at three photometric test wavelengths (302.0 nm, 395.0 nm and 512.0 nm). A total of 9 apparent absorbance results (each result represents the assigned value and its associated uncertainty) are provided in the Certificate of Calibration.

STRANASKA® CA2M 706
This reference material artifact is intended for the calibration and/or verification of the absorbance scales of molecular absorption spectrophotometers in the ultraviolet (UV), visible (VIS) and short-wave near infrared (SW-NIR) regions of the electromagnetic spectrum. Derived from the NIST SRM 931 series, it is comprised of three solution/cuvette filters which are provided in a protective canister for storage and transportation purposes. Each solution/cuvette filter is individually calibrated, relative to an air-only reference path, for apparent absorbance at four photometric test wavelengths (302.0 nm, 395.0 nm, 512.0 nm and 678.0 nm). A total of 12 apparent absorbance results (each result represents the assigned value and its associated uncertainty) are provided in the Certificate of Calibration.
