Niacin liquid filter

Niacin liquid filter (213 - 261 nm)

for checking the photometric accuracy in the UV range

Niacin (nicotinic acid) in hydrochloric acid is highly suitable for checking the photometric accuracy of spectrometers in the UV range. The Niacin spectrum shows a relatively broad maximum at the wavelengths 213 nm and 261 nm.

The Niacin filter solutions are filled and immediately fused under controlled conditions to become permanently airtight.

Application

The Niacin liquid filters are used for checking the photometric accuracy (absorbance) and the photometric linearity in the UV-range, according to the requirements of the European Pharmacopoeia and the United States Pharmacopeia (USP 857).

Typical scanlines of Niacin liquid filters, measured at a slit width of 1 nm.

Following Niacin Filter Sets und Single Filters are available:

S501	667S501	Filter-Set includes 6, 12, 24 mg/L Niacin and reference filter
Standard Measurement		Wavelengths: 213 nm and 261 nm Slit width: 1 nm; with DAkkS calibration certification
Possible Measurements		Wavelength: fix Slit width: 1 and 2 nm

Note

The individually measured absorbance values are free from any systematic errors. The measured data of the reference filter UV599 (hydrochloric acid measured against air) appears separately on the calibration certificate.

To check photometric linearity, perform the measurement with Niacin filters of different concentrations. List the measured absorbance values for each filter and each wavelength in a diagram and calculate the correlation coefficient.

To help you with the determination of the photometric linearity, we have created an excel file (tool) for the evaluation of your measurement values.
