Description
Type: Stray Light Standard, NaNO2
Wavelength Range: 380 to 400 nm
Unit Size: Each
Each Thermo Scientific Stray Light Standard stops transmitting light below a specific wavelength. Below this cut-off, any measured value can be attributed to instrumental stray light. A measured value of stray light that does not meet instrument specifications may indicate a problem with the instrument lamp and may result in analytical errors.The following standards are available for stray light measurements:
• Potassium Chloride, cutoff at 200nm
• Sodium Iodide, cutoff at 260nm
• Sodium Nitrate, cutoff at 390nmStray Light Standards are provided in permanently sealed quartz cuvettes. A water blank corresponding to each specific standard is supplied with every Stray Light Standard for performing blank readings.
