JM Science’s AQUACOUNTER AQL-22320 Automated Oil Evaporator System is an automated Karl Fischer Titrator System consisting of the AQ-2200 (coulometric titrator) and the EV-2000L (oil evaporator) units. This KF Titration System has been designed for analyzing moisture in difficult samples such as shale oil crude oil, grease, heavy lubricants, other oils and other difficult samples. Using an azeotropic distillation solvent like toluene or xylene, moisture can be evaporated at a lower temperature thus saving on expensive Karl Fisher reagents and lower maintenance costs since the titration cell remains clean and free of contaminants. This automated system allows the analyst to load the samples into the glass vials and then place the glass vials on the sample tray of the system. The operator only needs to push the “start” button once to begin the analyses.
An easy-to-use, reliable titrator includes free download software and RS-232 cable to connect to the customer’s computer. The Aquacounter COM-300A Automatic Titrator performs pH, acid/base, complexometric, redox, Karl Fischer, photometric, non-aqueous titrations and ISE (Ion-Selective Electrode) measurements. The unit can also determine TAN/TBN (total acid/total base) in oils and P and M (relating to water hardness) alkalinity. Additional features include one-touch calculations – with a statistics package – and over 30 files of built-in method memory. The unit stores up to 50 results in memory or downloads results to a laptop or desktop PC (download software is included). Balance and computer interfaces are standard for GLP (good lab practice) and ISO documentation. An optional Karl Fischer Kit add-on is now available which enhances flexibility in the use of this titrator for moisture determination.
