Import Tips
• Frequency range (0.1-10 THz) documentation confirms infrared optical radiation chemical analysis function
• Distinguish from radar/millimeter wave by specifying spectroscopic chemical identification capability
• Pharmaceutical PAT applications need FDA process analytical technology validation
