在十八(烷)基中導入了極性官能基的EP(EMBEDDED POLAR極嵌合)色譜柱有著容易選擇性地保留極性化合物的特長。我們可以了解其與通常的反相色譜柱的洗脫類型上的差別。但是,由于一般的市售極性嵌合選擇性色譜柱導入了作為極性基的含氮官能團,因此有著吸附酸性化合物以及在酸性溶離液下穩(wěn)定性較差的缺點。而Inertsil ODS-EP不但對于堿性化合物,對于酸性化合物也同樣能夠干凈地洗脫,可謂是理想的極性嵌合選擇性色譜柱。

Applications
Mobilgrease XHP 220 greases are used in a wide range of equipment including industrial, automotive, construction and marine applications. Their blue color enables easy verification of application:Mobilgrease XHP 005 and 220 are softer, high-temperature greases recommended by ExxonMobil for centralized grease application systems, gear lubrication, and where extreme-cold-temperature pumpability is important.Mobilgrease XHP 221 is recommended by ExxonMobil for use in industrial and marine applications, chassis components and farm equipment. It provides excellent low temperature performance.Mobilgrease XHP 222 is recommended by ExxonMobil for industrial and marine applications, chassis components and farm equipment. Its sticky formulation stays in applications longer.Mobilgrease XHP 223 is recommended by ExxonMobil for applications where good high temperature and anti-leakage properties are required. It is particularly recommended for severe truck wheel bearing applications or for rolling element bearings subject to vibration, or where higher speeds require a grease with higher consistency to provide channeling characteristics.Mobilgrease XHP 222 Special contains 0.75% molybdenum disulfide, is grey in color and is recommended by ExxonMobil for moderate duty service in industrial applications, chassis components and farm equipment. It also finds application in king pins, U-joints, fifth wheels and bucket pins.
