    CHEMOTRONIC III 1.3. Calibration The following turbidity calibrations can be used: Ac = automatic calibration, applicable to Std-program and user programs U1 – Max. sensitivity is a setting at 90 % of the max. clearness of the solution. Min. sensitivity is a setting at 10 % of the max. clearness of the solution. Pc = program specific calibration.
  • Page 8 CHEMOTRONIC III 1.3.1. Introduction This chapter is providing information on the basic concept of the cloud point measurements of resins for applications in printing inks. In lithography printing conventional oil-based paste inks perform best. These inks consist of resins, mineral oils, pigments and additives. Therefore the performance of these inks is highly depending on the compatibility of all these components.
  • Page 9 CHEMOTRONIC III The CHEMOTRONIC determines the cloud point of hard resins in solutions based on mineral distillates of analytical quality. To determine the cloud point accurately and reproducibly, the temperature of the test liquid must be cooled down under reproducible conditions until a reduction of transparency due to the effect of suspended particles, i.

  • Page 10: Operation Modes

    CHEMOTRONIC III Operation modes In accordance with the practical requirements of modern quality managment systems two operation modes were implemented into the instrument. The first mode called Prod-Mode includes a limited function set only and is intended for the quality control generally. The second mode called Lab Mode allows the access to the complete function set and is intended for the laboratory control or to adjust the Prod Mode.

  • Page 11: Change The Operation Mode

    CHEMOTRONIC III Prod-mode: This mode is meant for production control applications of the CHEMOTRONIC. In the quality assurance mode, only 1 standard is active and can be started. The upper row of push buttons on the front panel is inactive in this mode. 2.1.

  • Page 12: Testing Printing Ink Resins

    CHEMOTRONIC III Testing printing ink resins Statistically, specifications of raw materials can at best be only as consistent as the test procedures used to determine them. Test procedures should be based on scientifically approved principles, which means accurate test equipment for controlled test condi- tions such as heating and cooling temperature profiles, top temperature dwell time, agitation speed, turbidity determination, etc.

  • Page 13: Test Oils

    CHEMOTRONIC III 3.3. Test oils Resins used in printing inks today differ considerably in solubility and mineral oil tolerance. Therefore resins are tested in the liquid phase and subsequently the properties of the solution is also depending on the solvency of the test oil. Therefore a test oil must be made by appropriate processing of carefully selected oils in order to achieve a product of consistent analytical quality so that solvency deviations do not effect the measurements.

  • Page 16: Calibration

    CHEMOTRONIC III Calibration 6.1. Temperature calibration In the Chemotronic a powerful microprocessor system is installed for the control of all instrument functions. A 12 bit A/D-converter is used to convert the analogue inputs of the Pt 100 sensor into a digital signal. The input circuit is designed for automatic zero setting (auto zero) and automatic span setting (auto cal) by internal references.
  • Page 17 CHEMOTRONIC III 6.3.1. Turbidity calibration The software controlled infrared photo cell system offers two functions to calibrate the system and to determinate the cloud point reference. The user can adjust which turbidity point is recognized as the cloud point by executing a calibration procedure and choosing one of ten turbidity levels to fix the sensitivity within the range.
  • Page 18 CHEMOTRONIC III The turbidity measurement in the CHEMOTRONIC is performed by an infrared- photocell system taking both absorption and scattering infrared light passing through the sample under test into account. The measuring circuit is designed for full range measurements both of samples with a low turbidity and of samples with a high turbidity.

    CHEMOTRONIC III solution measured by the automatic calibration procedure. The factor can be varied between 90 % (clear) and 10 % (hazy). This adjustment is particularly of interest for solutions which show a slight turbidity only or those with a turbidity range. The standard test program is adjusted for automatic calibration, as it eliminates the necessity of turbidity standards.
  • Page 21 CHEMOTRONIC III For recalibration of the turbidity, the special polymer suspension FORMAZIN is recommended (available from the manufacturer/supplier). FORMAZIN primary standards are supplied in sealed dark brown 0.1 l bottles and can be used till 1 year after supply date. In order to prepare a secondary standard, one can dissolve a small portion of the primary standard in distillated water by using standard glassware.

  • Page 22: Function Test

    CHEMOTRONIC III Function test Chemical stability of resins, like that of many often chemicals, is highly dependent on storage conditions. Heat and light may break down the structure and the cloud point measurement will show random values. Therefore, a function test should be performed with a material that is chemical stable like stearic acid.

  • Page 23: Cloud Point Measurement Procedure

    The standard test tube is a straight tube with 22 mm diameter, 200 mm length and 1.2 mm thickness of the glass wall, made of borosilicate glass. These tubes are available from NOVOMATICS. The glass of the standard test tube is absorbing wave lengths shorter than 300 nm only so that nearly all transmission in the infrared region can pass through it without attenuation.
  • Page 24 CHEMOTRONIC III absorption at longer wave lengths and so for turbidity measurements a standard glass tube, available from your supplier, must be used. Summary: Switch on the instrument and watch the temperature display. The display is showing the mode of operation, which can be determined by the supervisor Make sure the temperature sensor is plugged into its socket on the rear.
