Starna Nicotinic Acid Solutions

 

.  Used for qualifying the absorbance scale and linearity in the Far UV region of the spectrum

.  Solutions of four concentrations of nicotinic acid in dilute hydrochloric acid permanently sealed by heat fusion in to UV grade quartz cells

.  The spectrum of nicotinic acid dissolved in dilute hydrochloric acid has peaks at 213 nm and 261 nm

.  A graph of measured absorbance against concentration of this reference will be linear if the absorbance scale of your instrument is linear

.  Instruments to be qualified should have a bandwidth of 2 nm or less. These references are calibrated at a bandwidth of 1 nm. Other bandwidths may be available on request
