Europa scientific have an excellent dual inlet machine using their own
design microinlet system. The instrument is a novel 120 degree sector
extended geometry design giving excellent dispersion, true stigmatic
focussing etc. Dr. Simon Prosser is responsible for the dual inlet systems.
I do not know whether or not Europa are connected to the 'net but will pass
on details of ISOGEOCHEM to Europa.
