自动荧光定硫仪
能量色散X射线硫含量仪
RX-620SA


RX-620SA determines total sulfur in petroleum products, such as gas oil, fuel oil, crude oil and naphtha, using energy dispersive X-ray fluorescence(EDXRF) method, which is an accurate, non-destructive, economical and yet quick method prescribed in ISO 8754 and ASTM D4294-03. Once a sample is set, the total sulfur is determined automatically in 300 seconds(typical). The model RX-620SA is a 12-sample carousel model. After its successful predecessors, this fourth generation has been developed to further improve the accuracy and ease of use.
RX-620SA 是按“能量色散X射线荧光光谱法（EDXRF） ”测定石油产品硫含量的仪器。可通用于车用汽油，柴油，原油，石脑油，渣油，润滑油基础油，液压油，喷气燃料和其他馏分油在内的碳氢化合物中的硫含量测定。适用于ISO 8754 ，ASTM D4294-03.，GB/T 17040的标准。测试过程简单高效，试验结果准确和重复性良好，是一种经济的无损测试方法。通常情况下，测试一组样品zei多要300秒，RX-620SA带有一个自动旋转的测试盘，可连续测试12个样品。作为“田中科学”的第四代产品，仪器性能有了进一步的提升，使用更简单灵活。

HIGH PRECISION: Pulse height analysis(PHA) is automatically carried out before each measurement to adjust the system. This innovative system design has further improved the precision.
精度高：高精度脉冲电子计数系统，精确而高效。

WIDE RANGE OF SAMPLES: Patented “Diamond Parameter Method” accurately compensates for measurement error caused by different carbon/hydrogen(C/H) ratio of individual sample. This state-of-art technology enabled measurement of wide range of samples of different C/H ratios with uncompromising precision.
测试范围广：独有的专利技术 “Diamond Parameter Method”,无论是轻油,原油,重油。从低浓度到高浓度,均能在短时间内通过简单的操作,高精度地测出硫分值。对于不同的碳氢化合物（C/H）也能自动补正



AMBIENT TEMPERATURE AND BAROMETRIC PRESSURE COMPENSATION: Compensation for ambient temperature and barometric pressure are made automatically to drastically minimize the drift. 对于环境的影响,可通过气压补正,温度补正进行自动调整。

AUTOMATIC CALIBRATION: Set certified calibration standards and start automatic calibration program to carry out automatic calibration. Either multiple point calibration at up to 12 points or two point calibration starts. 比对标准样品，仪器可进行自动的2点校正和多点校正。

CAROUSEL TYPE SAMPLE CHANGER WITH ACRYLIC COVER: X-ray shielding is by a metallic cover moving downward on the objective sample cell. Since the acrylic dust cover is not intended for shielding X-ray, it may be opened during a test, allowing access to sample cells in the cue.
自动旋转样品台：样品测试区（X射线区）有独立的金属护罩独立分隔，通过旋转平台一一更换，每一个样品都是独立测试的。即使在测试过程中也可以打开仪器外罩，更换或添加样品，不会有X射线泄露的危险，尤其适用于大量集中连续的样品测试。
