自動(dòng)熒光定硫儀

能量色散X射線硫含量?jī)x

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射線熒光光譜法（EDXRF） ”測(cè)定石油產(chǎn)品硫含量的儀器。可通用于車用汽油，柴油，原油，石腦油，渣油，潤(rùn)滑油基礎(chǔ)油，液壓油，噴氣燃料和其他餾分油在內(nèi)的碳?xì)浠衔镏械牧蚝繙y(cè)定。適用于ISO 8754 ，ASTM D4294-03.，GB/T 17040的標(biāo)準(zhǔn)。測(cè)試過(guò)程簡(jiǎn)單高效，試驗(yàn)結(jié)果準(zhǔn)確和重復(fù)性良好，是一種經(jīng)濟(jì)的無(wú)損測(cè)試方法。通常情況下，測(cè)試一組樣品多要300秒，RX-620SA帶有一個(gè)自動(dòng)旋轉(zhuǎn)的測(cè)試盤，可連續(xù)測(cè)試12個(gè)樣品。作為“田中科學(xué)”的第四代產(chǎn)品，儀器性能有了進(jìn)一步的提升，使用更簡(jiǎn)單靈活。

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：高精度脈沖電子計(jì)數(shù)系統(tǒng)，精確而高效。

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.

測(cè)試范圍廣：獨(dú)有的 “Diamond Parameter Method”,無(wú)論是輕油,原油,重油。從低濃度到高濃度,均能在短時(shí)間內(nèi)通過(guò)簡(jiǎn)單的操作,高精度地測(cè)出硫分值。對(duì)于不同的碳?xì)浠衔铮–/H）也能自動(dòng)補(bǔ)正

AMBIENT TEMPERATURE AND BAROMETRIC PRESSURE COMPENSATION: Compensation for ambient temperature and barometric pressure are made automatically to drastically minimize the drift. 對(duì)于環(huán)境的影響,可通過(guò)氣壓補(bǔ)正,溫度補(bǔ)正進(jìn)行自動(dòng)調(diào)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. 比對(duì)標(biāo)準(zhǔn)樣品，儀器可進(jìn)行自動(dòng)的2點(diǎn)校正和多點(diǎn)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.

自動(dòng)旋轉(zhuǎn)樣品臺(tái)：樣品測(cè)試區(qū)（X射線區(qū)）有獨(dú)立的金屬護(hù)罩獨(dú)立分隔，通過(guò)旋轉(zhuǎn)平臺(tái)一一更換，每一個(gè)樣品都是獨(dú)立測(cè)試的。即使在測(cè)試過(guò)程中也可以打開儀器外罩，更換或添加樣品，不會(huì)有X射線泄露的危險(xiǎn)，尤其適用于大量集中連續(xù)的樣品測(cè)試。
