| 3D POSITIONER |
The accuracy of measurements is determined by the spatial resolution of
the probe to the surface being measured. A motorized drive is controlled with a computer
to auto-scan and provide accurate probe position information. |
| COMPUTER |
These measurement systems are designed to be used with IBM type PC
computers and compatibles. The computer must have at least 3 PCI
expansion slots available for add-on boards (Framegrabber, A/D and
Motion Controller Board). The computer should have the WINDOWS XP
operating system installed. Applicable Electronics highly
recommends purchasing a computer with any system orders to avoid various
problems with PC architectural layouts and software conflicts. We
pre-load and test with boards and ASET. |
| SOFTWARE |
The ASET software is written for the WINDOWS environment in Visual C++.
The software controls system video, 3D-motion control, data acquisition and storage, video
storage and microscope focusing.Routines are also written for auto scanning of samples. |
| VIDEO |
Color or Black & White video images can be stored on disk. The ASET
software provides for vector data and graphic overlays on images. Images are stored in
.BMP format and are transportable to most common graphics software available. The video
system will run in PAL or NTSC. Images can be printed on a laser or color ink jet printer
as well. Images are displayed on the computer’s VGA monitor. A real time monitor is
also provided for better experimental control. |
| OPTICS |
A good microscope is vital for proper spatial resolution. An upright type
is very versatile and can be used for most work. Applicable Electronics sells a
motorized video zoom scope, VZS-1, designed for corrosion studies. It is an upright type
of microscope with zoom adjustment from 14X up to 90X magnification. Other lenses are
available for special needs. The system can also be used with an inverted microscope. |
| CALIBRATION |
The best way to calibrate the SVET electrode is to use a point source of
current. This requires accurate source placement. You will need an additional 3D
positioner (mechanical). SVET wire electrodes can be used as point sources of current;
though pulled glass microelectrodes are best. Applicable Electronics sells two kinds
of glass pipette pullers. One for making SVET calibration sources, one for making SIET
electrodes. |
| OSCILLOSCOPE |
An oscilloscope is necessary to monitor the probe signal. This will help
enormously if trouble arises. A 10 to 20 MHz model is sufficient. |
| STABLE PLATFORM |
An air table is best. Applicable Electronics sells an air table with
a 3.0’x 3.5’ work surface. It works with compressed air or nitrogen tank. It has
a drilled and tapped surface hole pattern for mounting equipment. |
| SHIELDING |
A Faraday cage around your experimental area is desirable.It is not
necessary for SVET work. For SIET work, it is necessary. Faraday cages made for the air
tables are also available. |
| DATA REDUCTION |
The program will convert data files to ASCII text format for easy
transport into commercial spreadsheets and plotting programs. |
| BATH ELECTRODES |
You will also need 6" of 99.99% Platinum wire for SVET and a dri-ref
electrode for SIET/SPET work. |
| EXTRAS |
You will need some mechanical parts such as posts and postholders, glass
electrode AgAgCl pellet holders, sample holding platform, small optical rails for mounting
things, spare connector pins for the probes and wires. Machining of custom parts is also
available by contacting Science Wares. |
| CHEMICALS |
You will need 10 ml of Hydrogen Hexachloroplatinate 8 wt% solution and 1
gm of Potassium Dicyanaurate for plating electrodes while doing SVET or SPET work. SIET
work will require LIX (liquid ion exchangers) available from various companies. |
