POUR POINT AT 1 ℃ INTERVALS FOR HIGHER YIELD IN PROCESS:
The conventional PP test methods yield a rough PP numbers of multiple of 3 ℃, and thus higher resolution in PP determination has been long awaited for more elaborate process control. With the patented Air Pressure method, PP can be now determined at 1 ℃ intervals with high accuracy, since the disturbance on the formation of wax crystal structure through the test process is at a minimal level. When PP is measured at 1 ℃ intervals, typical repeatability and reproducibility are 1 ℃ and 2 ℃, respectively.
传统的“倾斜法”是按3℃间隔测试样品的倾点,新的标准按1℃间隔测试样品,仪器测试精度大于试验标准测试规定,可以保证试验结果的精度更高。“气压法”也可有效避免降温过程中,样品的蜡状析出和冰晶体对结果的干扰。
EASY SAMPLE HANDLING: 采样少,易操作
Since the required specimen volume is a mere 4.5 ml and the specimen cup is a test-tube type removable jar, the sample handling is extremely easy. 样品仅需求4.5毫升,玻璃小型样品杯是一个可取放的瓶状试管,操作极其简单。
EASY, QUICK, AND PRECISE PP/CP DETERMINATION:
Just set up the specimen, set test parameters, and then press the START key to start a test. Specimen is cooled at the steepest possible rate without affecting the formation/growth of wax crystal, which has been known to be critical in PP/CP determination. For fuel oils, the specimen may be even pre-heated automatically and then cooled for CP/PP determination, which further improves test throughput.
选好样品后,输入测试参数,预期的倾/浊点数据,按下“开始”键。测定过程由仪器自动完成,无需人工干预。当到检测出倾点后,样品被自动加热至与室温一致。从而可在短时间内进行多组测试。
相较于传统测试方式,“气压法”的效率更高,一般只要传统方式的1/3 或 1/2的时间,就可以完成测试。可在短时间内进行多组测试。
