Polishing Chamber

• Second Kinetic Chamber Further Polishes The Sample

• Minimal Lag Time

• Flow Rate Of Second Chamber Can Be As Low As 10% Of The Flow Of The First Chamber

Slide 10

Polishing Chamber

• First Chamber-16 x 1 Expansion– Prevents Excessive Pressure Drop In Fast Loop

• Second Chamber 256 x 1 Expansion– Greater Pressure Drop As Sample Exits The Tube

Increased Pressure Drop Increases Cooling
