The AMI-300 comes standard with a highly linear TCD. In addition to the TCD, AMI instruments have been delivered with a wide range of auxiliary detection devices.

Choices of auxiliary detectors have included:

Any detector that provides an analog output or which can communicate through DDE, Serial ports, OPC, ActiveX, or other Windows protocols can be triggered by the AMI-300. The degree to which the auxiliary detection device is to be integrated with the instrument can be specified and incorporated into the control software.

Seven (7) Standard Procedures - Pulse chemisorption, TPR/TPO, TPD, TPRx, treatment, pulse calibration, and flow BET. Ability to link 99 procedures into one experiment.
Three Independent Gas Sources - In addition to a carrier gas and a treatment gas, the AMI-300 provides one additional independently controlled auxiliary gas inlet which can be blended with the carrier gas or treatment gas.
Ten (10) Gas Ports - Gas ports located on the back of the instrument minimizes the time expended changing gases. Four ports each for treatment and carrier gases. Two ports are available for gas blending or auxiliary gases. Additional ports can be added.
Electronic Flow Controllers - Unit uses high quality linear mass flow controllers to display and control gas flows. Flow rate span is 0-50 Sccm (standard). Other ranges are available upon request.
Interchangeable Valve Loops - Provide an easy way to reach the appropriate level of sensitivity for different samples.
Liquid Vaporizer - Unit can be equipped with a heated sparger-type saturator for easy introduction of volatile liquids.
High Temperature Furnace - Temperature up to 1200ºC; with sub-ambient cooling, the lower limit is -130ºC. Furnace can be linearly ramped from 1ºC/min to 50ºC/min.
Air Cooling - Cools the furnace rapidly for quick sample turn around.
Sample Temperature - Measured by a moveable thermocouple placed at the top of the sample bed.
Various Sample Holders - Unit accommodates a variety of quartz U-tubes sized to accommodate various catalyst volumes and sizes: straight, bubble, preheat, monolith. Samples may be powders, pellets, extrudates or honeycomb cores.

Easy Sample Loading - A movable furnace allows easy removing and loading of the sample holder.
Trap - A trap that may be filled with a desiccant or used as a cold trap is provided downstream of the sample holder in order to remove condensables before the TCD.
Heated Null Station - Ensures accurate calibration pulses without contact with the sample.
Injection Port - A syringe injection port is provided for exact loop volume calibration.
Heated Lines - All lines, valves, and parts of the liquid vaporizer are heated to prevent condensation.
Thermal Conductivity Detector - Highly reliable 4-filament TCD used to quantify gas uptakes. Excellent linearity, accuracy, sensitivity, and stability. Several filament options are available.
Direct Mass Spectrometer Link - MS data can be integrated in real-time with AMI-300 data using Direct Data Exchange (DDE).
Auxiliary Detectors - Can accept any auxiliary detector providing a voltage analog output, such as a flame ionization detector (FID).
Low Internal Volume - Low volume valves and 1/16” lines are used to reduce void volume and minimize peak spreading.
Materials of Construction - Seals and materials are custom engineered to meet your specifications.
Safety Features - Among others: independent over-temperature protectors for furnace, resealable pressure relief valves, check valves, circuit breakers, and fuses. System is designed to fail in safe mode.
Fliter -  ensure to eliminate carryover of light particles of sample into the instrument manifold with the provision of filters and the operator is able to clean or replace the filters.
