Standard "wet" wide angle (WA) skimmer cone with a 0.7 mm orifice used on the AttoM, both on the standard and ES interfaces. The cone is made from Nickel but has a Platinum tip.
Can also be used on the Nu Plasma & Nu Plasma II standard and MKII ES interface as it can enhance low mass range elements (Li & B). Best used with the 319-593 sample cone which is also Platinum tipped.
