iS50 ATR module features
The iS50 ATR module features include:
•
Diamond crystal
. A robust, durable material for ATR sampling. The crystal is brazed to
the crystal plate to maximize strength and chemical resistance.
• Crystal plate.
The stainless-steel mount for the diamond crystal. The crystal plate is
permanently sealed to protect internal mirrors and optimize purge performance.
•
Sampling plate
. This plate can be removed for cleaning or sterilizing.
•
Pressure tower
. The pressure tower is a mechanical press used to achieve uniform contact
between a solid or powder sample and the ATR crystal (up to 267 N or 60 lbs of force).
The arm swings out of the way for easy access to the sampling area. The pressure tower
can be removed when analyzing only liquids.
•
Pressure tip.
The ATR module comes with two stainless-steel tip styles that can be used
to optimize contact between the sample and the diamond crystal. The extra tip can be
stored on the pressure arm.
•
ATR Touch Point
. This button automatically configures the spectrometer for ATR
sampling. The Touch Point LED shows the status of the ATR module. The LED has
three states described below.
