Semi-automatic
AutoSpotter Model SES 3202/IS-02
|
|

SES Model 3202 AutoSpotter
for TLC/FID techniques is a precision instrument specially developed for
applying sample solutions onto the sintered silica gel surface of a
Chromarod. The smaller and more concentrated the sample spot, the better
the resolution obtained after development of the Chromarod in a TLC
chamber (3201).
The reproducibility of quantitative and qualitative analyses with the
IATROSCAN is closely related to the accurate application of a known
quantity of sample onto the surface of a Chromarod in the form of a micro
spot.
With the "AutoSpotter" it is possible to apply between 0.020 and
10 micro liters of sample solution. The spotting is electronically
controlled through a small external microprocessor module, with a
precision of better than 0.5 %.

Features:
|
|
|
|
 | Quantity of sample is digitally
controlled by a stepping motor, driving a precision syringe.
|
| Accurate, automatic indexing of the
syringe to the next sample application position.
|
| Automatic dispensing of sample when each
indexed position is reached.
|
| Automatic control of 2 wash-cycles using
the "Wash-Button"
|
| Precise selection of sample quantity by
pre-selection of syringe piston stroke.
|
| Constant controlled speed of pick- up
and discharge of sample quantity prevents the formation of gas bubbles
in volatile eluents.
|
| The "AutoSpotter" can apply
the sample in successive aliquots thus allowing the solvent to
evaporate prior to dispensing the next aliquot of the sample. this
avoids diffusion of the sample spot and prevents deterioration of
resolution. In this way large amounts of sample can be applied on
Chromarods to improve the sensitivity of analyses. |

Fully automatic
and programmable Sample Spotter Model
SES A4100 for
CHROMARODSÒ
|
|

The Model A4100
is also suitable for the spotting on TLC plates. As a user of IATROSCAN,
you sure would like an improvement of sample spotting .
In the analysis,
scientists aim at automation as much as possible. The targets are time
saving, accuracy and the elimination of operating errors. This Spotter
makes the sample spotting on Chromarods and TLC-plates fully automatic.
The new Spotter reduces the
time and work for spotting to the programming of the spotting methods and
putting the solvent and sample vials into the associated racks
respectively.
The spotting is fully programmable
& automatic. The user can do other important jobs during this
time. The Spotter makes the programmed sample spots unattended on its own
and generates an signal when spotting is finished.
|
|
|
|
|
The spotter reaches its accuracy by
digital computer control and by four stepping motors with accurate
spindles. So all needed movements for sample taking out of membrane
closed bottles, up to exact guiding of the syringe to and on the
Chromarods, can be made. There are 25 places in the sample array and
some other arrays for standards and some for solvents to clean the
syringe . The waste is automatically put into membrane closed vials.
|
|
Rows of standard samples with
decreasing or increasing concentration, and the selection of samples
can be programmed. Unknown samples and known standards can be put on
same rods etc.
|
|
The Spotting speed and the different
sample amounts can also be selected. The samples can be spotted in
small aliquots , such that the spotting point will be as small as
possible for best resolution after development.
|
|
All parameters for the movements can
be programmed prior to real spotting of the samples on Chromarods or
TLC-Plates. A small jet of air, nitrogen or another inert gas would
speed up the solvents evaporation. The tube for this is incorporated
in the head for syringe movement a small air pump could be build in as
an option.
|
| The template for the Chromarods is built in a way
that it can also be used for TLC plates. The SES-A 4100 has a double
use for the Laboratories that analyze with both techniques. So the
investigation has a double advantage. |
|
These new automatic AutoSpotter convert the TLC/FID technique with
IATROSCANÒ to modern instrumentation. The
Analyses with Iatroscan becomes favorable in maintenance and price with
this full automatic spotting. |
