COMPONENTS OF THE ICT™ UNIT
The AEROSET System measures Na
+
, K
+
, and Cl
-
simultaneously using
Integrated Chip Technology™ (ICT). ICT uses solid state Ion-Selective
Electrodes contained in a single chip (ICT Module) which reduces the
maintenance required.
The ICT Module is contained in the ICT Unit. The ICT Unit can move
into position over the ICT Reference Solution cup to aspirate ICT
Reference Solution, or over the Reaction Carousel to aspirate the
diluted sample. The components of the ICT Unit and other components
used to measure ICT assays are described in the following table.
Component Description
ICT Module The ICT Module is an integrated chip composed of a
Na
+
, K
+
, Cl
-
, and Reference electrode. (The module is
located in the ICT Unit.)
ICT Aspiration
Pump
A 1 mL syringe drive pump that aspirates samples or ICT
Reference Solution into the ICT Module for
measurement, then moves waste into the water bath/
waste overflow area when measurement is complete.
(This pump is located behind the ICT Pump access door.)
ICT Reference
Solution
ICT Reference Solution is measured before and after
each sample to create a baseline for checking for
electrode drift. The second read measurement is used to
calculate the sample result. (This Bulk Solution is placed
on a weight platform behind the front-right door.)
ICT Reference
Solution Pump
A 1 mL syringe drive pump that aspirates ICT Reference
Solution from the bulk bottle, through the ICT Reference
Solution preheater, and into the ICT Reference Solution
cup. Once measurement is complete, this pump aspirates
the ICT Reference Solution from the cup and moves it
into the water bath/waste overflow area. (This pump is
located behind the ICT Pump access door.)
ICT™ Reference
Solution Preheater
This preheater warms the ICT Reference Solution to
37°C, before it is used to fill the ICT Reference Solution
cup. (The ICT Reference Solution preheater is a narrow
metal tube located in the water bath.)
ICT™ Reference
Solution Cup
Preheated ICT Reference Solution is aspirated from this
cup and measured by the ICT Module. (Located beneath
the ICT Probe when the ICT Unit is in the home
position.)
Water Bath/ Waste
Overflow
The liquid waste from the ICT Unit and the ICT
Reference Solution cup is dispensed into this waste area,
located on the right-hand side of the Reaction Carousel.
The liquid waste is removed from the Analyzer through
the Low-Concentration Waste tubing.
• If desired, take students to the
instrument and point out
components, then discuss at
desk.
