Select the Temperature Unit (°C or °F) at the top of the window. Enter the Upper Limit, Lower Limit and/or Centerline values for the corresponding run modes.
  • Page 15 70Xi Cold Flow Properties Laboratory Analyzer User Guide Specification Limits for Non-QC Samples Upper and lower limits can also be assigned to sample not designated for QC purposes. Such limits may be internal production specification and hence useful for monitoring. Alerts are accordingly generated by the analyzer in case these limits are exceeded.
  • Page 16 70Xi Cold Flow Properties Laboratory Analyzer User Guide Control Charts and Trend Graphs Trend graphs (i.e. time vs. test results graph) can be constructed for both QC and non- QC samples. Such a plot illustrates the test results of a particular sample (of a specific sample ID) over time, and can serve as a trending plot.

    70Xi Cold Flow Properties Laboratory Analyzer User Guide H o w t o C a l i b r a t e V i s c o s i t y Viscosity can be calibrated by using jet fuel standards with known KV values. It is recommended to test at least two jet fuel standards with different viscosity.
  • Page 25 70Xi Cold Flow Properties Laboratory Analyzer User Guide CAUTION! Only use jet fuels as viscosity calibration standards. Do not use base oils or other materials to calibrate the viscosity. 3. When the test has completed, you may choose to do another run of the same sample (RE-RUN), test the next sample (NEXT), or finish the calibration (DONE CALIBRATION).

  • Page 30 “fill to this line” mark on the bottle to use as a guide when filling with desiccant. Lightly tap the bowl to settle the desiccant. NOTE: Phase Technology desiccant packs are pre-measured so that each one contains the exact required amount. There should be no excess. Desiccant is now better packaged with a stronger vacuum pack seal to ensure there is less exposure to air and moisture.
  • Page 31 Keep the lid of your analyzer closed and latched when not in use to prevent humid air from entering the purge system through the chamber inlets. CAUTION! Use desiccant provided by Phase Technology only. Use of other desiccant or recharging desiccant will VOID WARRANTY. Ordering information:...

    The certificate specifies the allowable deviation from the average measurement over a range of standard results. Every new Phase Technology analyzer is shipped with a Certificate of Calibration which details the specific customer, serial number, test methods and precision (repeatability and reproducibility), date of calibration, and date for next recertification.
  • Page 33 70Xi Cold Flow Properties Laboratory Analyzer User Guide Is Phase Technology preventive or scheduled maintenance service the same as general, routine maintenance? No, routine maintenance consists of procedures that are a part of good laboratory practices. These include cleaning the test chamber, sample cup and optic lens. Replacing desiccant and performing certain diagnostic tests are also part of routine maintenance.

  • Page 34: Appendix D. Understanding & Using Phase Plots

    ASTM D5773 test method. Phase Technology’s 70Xi analyzer performs a cloud point test in two stages. First, the sample is cooled at a fast rate as the optics system looks for crystal formation and signal rise. On a cloud point phase plot, this can be seen as the blue line moves from left to right.
  • Page 35 ASTM D5972 test method. During a freeze point test, Phase Technology’s 70Xi analyzer cools the sample relatively quickly until wax crystals begin to form. On a freeze point phase plot, this can be seen as the blue line moves from left to right.
  • Page 36 70Xi Cold Flow Properties Laboratory Analyzer User Guide In a pour point test, the sample starts off in a wax-free liquid state, and is then cooled. As it cools, it becomes more viscous as wax crystals begin to form. Pour point is the minimum temperature at which the liquid still flows before gelling or becoming sufficiently viscous and immobile under the test conditions.
