What are the typical interferogram maximum peak bench parameters for transmission?

Environment

  • Nicolet iS5

  • Nicolet iS20
  • Nicolet iS50
  • Nicolet 380
  • Nicolet 6700
  • Nicolet Summit

Resolution

From the menu bar, select Collect > Experiment Setup > Bench and set the parameters indicated in the table for your instrument:

Instrument Velocity Gain Aperture Size Transmission Accessory in sample compartment Expected interferogram height
iS5 0.4747 1 100 iD1 7.0-8.0 Volts max
iS10 0.4747 1 Open SMART Omni 7.0-9.0 Volts max
iS20 0.4747 1 Open SMART Omni 5.0-9.0 Volts max
iS50 (default Main Experiment file) 0.4747 1 230 None 8.0 Volts max top DTGS KBr detector amplitude
iS50 Built-In ATR (KBr Beamsplitter) 0.4747 1 230 NA 1.5 to 2.5 Volts Max
iS50 Built-In ATR (Solid Substrate Beamsplitter) 0.4747 8 230 NA 1.0 to 4.0 Volts Max
Nicolet 380 0.4747 1 Open None 8.0-9.0 Volts max
Nicolet 6700 0.6329 1 100 None 6.5-8.0 Volts max or better for DTGS detector
Summit / Summit Pro / Summit Lite / Summit X 0.4747 1 100 iD1 7.0-8.0 Volts max
