This accessory provides outstanding throughput for ATR analyses that require high sensitivity. The unique, see-through purge cover permits easy and consistent placement and replacement of the sample holder. The removable sample holder is simple to operate providing even pressure as it securely presses the sample to the crystal. A thumb-operated gear provides control of the 25°-75° angle of incidence range.

The Research-Grade Vertical Variable Angle ATR is designed exclusively for use with Nicolet FT-IR spectrometers. This accessory provides outstanding throughput for ATR analyses that require very high sensitivity. The unique, see-through purge cover permits easy and consistent placement and replacement of the sample holder. The removable sample holder is simple to operate providing even pressure as it securely presses the sample to the crystal. A thumb-operated gear provides control of the 25°-75° range of angle of incidence. Once aligned during installation, the accessory needs very little adjustment between angles of incidence. Sample plates are interchangeable, and several crystal materials and angles are available to accommodate specific applications.
