提供美國(guó)WILKS公司InfraCal CVH水中含油分析儀（紅外油脂分析儀/總石油烴分析儀），國(guó)WILKS公司InfraCal CVH水中含油分析儀國(guó)內(nèi)代理銷售。 美國(guó)Wilks公司是世界的紅外設(shè)備供應(yīng)商，在紅外光譜領(lǐng)域有很強(qiáng)的技術(shù)積累。Wilks公司的InfraCal系列水中含油分析儀，包括HATR-T2，CVH和CH三個(gè)型號(hào)，都已經(jīng)被認(rèn)為是測(cè)量TOG/TPH，即總油脂含量、總石油烴含量的標(biāo)準(zhǔn)儀器，被國(guó)內(nèi)外眾多石油化工行業(yè)的實(shí)驗(yàn)室采用。
InfraCal CVH水中含油分析儀采用EPA方法413.2和418.1項(xiàng)或ASTM標(biāo)準(zhǔn)測(cè)試法D7066-04項(xiàng)，對(duì)應(yīng)的提取溶劑分別為氟利昂，四氯乙烯，S-316，AK-225或其他溶劑進(jìn)行萃取，這些提取溶劑的特點(diǎn)是都重于水，提取后溶劑沉于水底，再采用相關(guān)方法提取出來(lái)。由于在分析過(guò)程中沒(méi)有蒸發(fā)環(huán)節(jié)，因此CVH具有更高的測(cè)量。分析儀配備有一個(gè)內(nèi)置的凹槽，整個(gè)分析需要不到10分鐘，儀器可為2 ppm。 InfraCal CVH的特點(diǎn) 1、儀器操作簡(jiǎn)單快捷，人性化設(shè)計(jì)，響應(yīng)快速，性能穩(wěn)定； 2、在操作時(shí)將裝有待測(cè)樣品的比色皿至于儀器中進(jìn)行測(cè)量即可； 3、測(cè)量時(shí)間在10-15分鐘內(nèi)，包括樣品前處理； 4、測(cè)量范圍大，可檢測(cè)2-4000ppm之間的濃度； 5、可檢測(cè)樣品中油類和芳香烴類物質(zhì)的含量 6、可選用多種萃取溶劑，例如全氯乙烯,氟利昂-113, AK-225 orS-316等等 7、各種測(cè)試TOG/TPH的場(chǎng)合均可使用 InfraCal CVH水中含油分析儀的原理 Infracal型TOG/TPH紅外分析儀是基于快速測(cè)定水和土壤樣品中總油脂（TOG）和總石油烴（TPH）濃度的紅外光譜方法，其工作原理合朗伯-比爾定律。即用一束強(qiáng)度為I0的特征紅外光照射樣品，由于油脂對(duì)特征紅外光產(chǎn)生吸收，光強(qiáng)度會(huì)減弱為I，樣品對(duì)特征紅外光的吸光度則為A=lg I0/I。根據(jù)光吸收的朗伯-比爾定律，吸光度與樣品中油脂濃度（C）的關(guān)系為A=abC，其中a為吸光系數(shù)，b為樣品池厚度，即樣品的吸光度與油脂濃度成正比。通常廠家出廠時(shí)已經(jīng)用一組溶度已知的待測(cè)樣品建立了標(biāo)定體系，用戶可以得知吸光度與油脂濃度的關(guān)系式，根據(jù)該關(guān)系式和被測(cè)樣品的吸光度，可以求出被測(cè)樣品中的油脂濃度。 InfraCal CVH技術(shù)參數(shù) 類型：固定濾光片濾光測(cè)試儀 規(guī)格：6.5×6.5×5英寸（165×165×225mm） 重量：4.5磅（2.0kg） 顯示：4位7段紅色LED屏，字高度5/8英寸 電源要求：電壓12V直流，+2% 功率：7.5瓦，標(biāo)準(zhǔn)5瓦 輸入接口：switchcraft 760或類似插頭，為正 建議電源：交流電源；交流/直流轉(zhuǎn)換器類型（標(biāo)配） 12v自動(dòng)電池連接器插頭（選配） 便捷式12v電池組（選配） 標(biāo)準(zhǔn)使用測(cè)量范圍： 水：2-1000ppm（用于10：1的萃取率） 土壤：3-5000ppm（用于1：2的萃取率） 可用萃取溶劑：氟利昂，全鹵代烴，S-316,AK-225 或其他可透過(guò)溶劑 分析時(shí)間：10-15分鐘，包含萃取過(guò)程 運(yùn)行溫度范圍：40華氏度（4攝氏度）到110華氏度（45攝氏度） 用戶選擇性校準(zhǔn)：0點(diǎn)平衡調(diào)節(jié) 多20點(diǎn)曲線擬合法校正 儀器可重復(fù)性+/-1ppm CVH紅外分析儀測(cè)定TOG/TPH的使用場(chǎng)合 ---在近海石油平臺(tái)上對(duì)生產(chǎn)用的樣品水進(jìn)行分析 ---監(jiān)控?zé)捰蛷S排放物、廢水處理或工業(yè)裝置 ---測(cè)定油/水分離系統(tǒng)的效率 ---地下儲(chǔ)存罐周圍的土壤指標(biāo)研究 ---測(cè)量預(yù)清洗金屬部件表面上的殘存油 ---測(cè)定回收溶劑的純度水平 ---其它對(duì)水或土壤進(jìn)行現(xiàn)場(chǎng)測(cè)定的場(chǎng)合 InfraCal Model CVH詳細(xì)規(guī)格參數(shù) Instrument Te | Fixed Filter Infrared yzer, Model CVH | ytical Wavelength/Wave Number | 3.4 μm, 2930 cm-1 | Power Requirements | 12 Volts DC, 2.0 amps, 12 Volt battery pack or adapter available | Power Supply | Universal AC/DC | Weight | 4.4 lbs.
