GFS In-Spec : In-Spec® Visible Standards

In-Spec® Visible Standards

The In-Spec® Visible Standards are designed for use in the visible range of the spectrum. With 6 different stock solutions of varying concentrations you should be able to find a solution that is close to the values that you see from your samples. If you need more exact values we can usually create a custom solution to your specifications. Please see our Custom Standards page for more information.

Advantages

Accurate
NIST Traceable
Stable - a consistent suspension
Easy-to-use - No Mixing and no dilution required
Flexible - Use at multiple wavelengths specific to your current testing
Non-Toxic - No concerns over handling, liability, storage and disposal

-Basics of In-Spec-

The table below lists a representative value for each solution at the given wavelength. The values were obtained using a 10mm quartz cuvette. The values are not exact lot to lot but will help you decide which value will work for you. We can also provide data for other pathlengths.
