The IA9300 provides a range of facilities as the 9200 with the following
exceptions:
Only one pre-programmed ramp rate is available i.e. 1.0 C/per min.
Six melting points may be stored in the resident memory per batch.
Three additional LED indicators are installed in the head to facilitate
ease of assignment of recorded melt points to particular capillaries.
The number of batches that can be recorded in the memory is reduced
to 500.
4.4.1 Mode of Operation.
All sections of the Operating Instructions pertaining to the IA9200 can be
applied to the IA9300 with some exceptions. Up receipt of the instrument
please turn to page 15 and follow the instructions, taking care to substitute the
following changes.
Section 4.3.9 Select Ramp rate.
Method 1 – Only the 1.0 /per min ramp is pre-selectable. All other ramps must
be keyed in as per Method 2.
Section 4.3.10 Analysis and Storage of Melt points.
Melt points are stored in memory by selecting the appropriate capillary with the
TS (Tube Select) key until the L.E.D corresponding to the selected tube is
illuminated and then recording the temperature in memory by operation of the
key Two values of melt point per capillary may be recorded and these
will be indicated by the two L.E.D‟s associated with the TS key.
Selection 4.3.11 recall and Processing Information.
a) Review of current malt batch.
This is obtained by successive operations of the key. Repeated
operation of this key will display the batch parameters in the following
sequence.
1) Melt points 1 and 2 – Capillary 1
2) Melt points 3 and 4 – Capillary 2
3) Melt points 5 and 6 – Capillary 3
The display will show the temperature of each successive melt point and the
L.E.D associated with each capillary and the TS key will show which of the
stored temperatures is being displayed.
Store, Recall and Print instructions remain unchanged.
