Calibration SpectroStandards® Single Bottle Units
Formulated with unsulfonated organo-metallic concentrates and diluted to concentration with sulfur-free lubricating oil, 20cSt. viscosity. Ideally suitable for instrument standardization procedures by XRF, AA, ICP or AE applications where the presence of sulfur potentially presents interference issues.
Quality Control and Drift SpectroStandards® Formulations
Quality control and drift standards are used to adjust for any changes in instrument sensitivity over a given term of operation, as determined by each laboratory, and to reduce or eliminate the need to effect time consuming and costly recalibrations. High purity polysulfide formulations have long shelf lives and are resistant to degradation. They are formulated from a concentrate and provided in convenient one liter size bottles to ensure uniform consistency and dispensing freshly prepared quantities as required. Drift corrections are generally performed whenever the quality control data moves beyond acceptable limits. With multiple instruments, Quality Control and Drift standards are ideally applicable to multiple x-ray instrument laboratories, inter-laboratory and plant installations for uniformity of performance and cost effectiveness by drawing from liter size bottle quantities.
