Titration systems are available to measure Yeast Assimilable Nitrogen (YAN). These systems include a mini-titrator designed specifically for measuring formol nitrogen in wine. Potentiometric titration systems can measure a wide range of parameters are available; including one that has wine parameters pre-programmed into the meter. The potentiometric titrations systems have a precision dosing pump for precise dosing of a titrant. These systems use a pH probe determine the endpoint.
Solutions for nitrogen measurement include the calibration solution and fill solution for the pH electrode used with the titrators.
Accessories include a COD reactor used to digest the sample when measuring total nitrogen by photometric analysis. Other accessories are a fixed range automatic pipette along with replacement parts for the mini-titraor.
Wastewater treatment benchtop photometers include the total nitrogen parameter along with other key water quality parameters including COD, nitrate, and ammonia. All benchtop have a digital pH electrode input allowing it to be used as a traditional pH meter.
Spectrophotometers are available that have nitrogen method in several ranges pre-programmed into the meter. The spectrophotometer offers the highest precision due to the quality of the optical system that has a wavelength accuracy of +/- 1.5 nm. The spectrophotometer allows for custom methods to be used as well.
Reagents for the photometric analysis along with reagents for formol number titration are included in this category.
Electrodes & Probes
Potentiometric titration systems use a pH electrode for determining the pH endpoint of a formol (YAN) titration. The pH probes include the one supplied with the mini-titrator and a pH electrode for wine that uses the Hanna’s Clogging Prevention System (CPS) technology. The CPS technology has a ground glass junction with a movable sleeve that allows for cleaning of any solids.
