The Edwards XDS 46i shares many of the same features of the XDS35i but with a peak speed of 40 m³h^-1. The pump has been optimized for maximum pumping speed at inlet pressures between 1 mbar and 10 mbar, making it ideally suited for LCMS and ICPMS applications requiring higher pumping speeds. 

The C variant has been modified so that it is more suitable for use on vapor handling processes and may be used in some applications using corrosive substances. The C version is fitted with Chemraz® internal valve pads and stainless steel exhaust port. Edwards nXDS Brochure
