提供美國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WILKS公司InfraCal CVH水中含油分析儀國內代理銷售。 美國Wilks公司是世界的紅外設備供應商，在紅外光譜領域有很強的技術積累。Wilks公司的InfraCal系列水中含油分析儀，包括HATR-T2，CVH和CH三個型號，都已經被認為是測量TOG/TPH，即總油脂含量、總石油烴含量的標準儀器，被國內外眾多石油化工行業的實驗室采用。
InfraCal CVH水中含油分析儀采用EPA方法413.2和418.1項或ASTM標準測試法D7066-04項，對應的提取溶劑分別為氟利昂，四氯乙烯，S-316，AK-225或其他溶劑進行萃取，這些提取溶劑的特點是都重于水，提取后溶劑沉于水底，再采用相關方法提取出來。由于在分析過程中沒有蒸發環節，因此CVH具有更高的測量。分析儀配備有一個內置的凹槽，整個分析需要不到10分鐘，儀器可為2 ppm。 InfraCal CVH的特點 1、儀器操作簡單快捷，人性化設計，響應快速，性能穩定； 2、在操作時將裝有待測樣品的比色皿至于儀器中進行測量即可； 3、測量時間在10-15分鐘內，包括樣品前處理； 4、測量范圍大，可檢測2-4000ppm之間的濃度； 5、可檢測樣品中油類和芳香烴類物質的含量 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、各種測試TOG/TPH的場合均可使用 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。即用一束強度為I0的特征紅外光照射樣品，由于油脂對特征紅外光產生吸收，光強度會減弱為I，樣品對特征紅外光的吸光度則為A=lg I0/I。根據光吸收的朗伯-比爾定律，吸光度與樣品中油脂濃度（C）的關系為A=abC，其中a為吸光系數，b為樣品池厚度，即樣品的吸光度與油脂濃度成正比。通常廠家出廠時已經用一組溶度已知的待測樣品建立了標定體系，用戶可以得知吸光度與油脂濃度的關系式，根據該關系式和被測樣品的吸光度，可以求出被測樣品中的油脂濃度。 InfraCal CVH技術參數 類型：固定濾光片濾光測試儀 規格：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，標準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/直流轉換器類型（標配） 12v自動電池連接器插頭（選配） 便捷式12v電池組（選配） 標準使用測量范圍： 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 或其他可透過溶劑 分析時間：10-15分鐘，包含萃取過程 運行溫度范圍：40華氏度（4攝氏度）到110華氏度（45攝氏度） 用戶選擇性校準：0點平衡調節 多20點曲線擬合法校正 儀器可重復性+/-1ppm CVH紅外分析儀測定TOG/TPH的使用場合 ---在近海石油平臺上對生產用的樣品水進行分析 ---監控煉油廠排放物、廢水處理或工業裝置 ---測定油/水分離系統的效率 ---地下儲存罐周圍的土壤指標研究 ---測量預清洗金屬部件表面上的殘存油 ---測定回收溶劑的純度水平 ---其它對水或土壤進行現場測定的場合 InfraCal Model CVH詳細規格參數 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.
