In the PDF, if you scroll down to page 4, you will find a chart listing various performances of several thrusters, starting from 0.5 N to 220 N. If you look at that last one, it actually lists the fuel as "LMP-103", not "LMP-103S", and the exit velocity listed is 2.8 km/s for a specific impulse of 285 seconds!
Is this a typo? Or is there some new derivative fuel lurking out there that has this amazing performance? I hope so, and tend to think so because that listed Isp is a rather big jump from the others. I really hope it is accurate.
