Spectrophotometer mounting a large-size color LCD, which
is simpler to use and higher in dependability.
High resolution satisfying European Pharmacopoeia (spectral
bandpass: 1.5 nm).
Trace-amount measurement in biotechnological field, etc. can be carried out
using optional 50, 25 and 5 micro cells.
Stable optics due to double beam
In double beam design, the energy of the light source is
divided into two with a half mirror so that one passes through the reference
side, and the other through the sample side, which is unavailable with the
single beam design.
Since the reference-side energy is also incident on a detector, photometry is
carried out on the basis of this signal. Therefore, an energy change in the
light source can be compensated to ensure stable measurement for a long time.
Incorporation of stigmatic concave diffraction grating
The optics of this instrument adopts the Seya-Namioka
monochromator widespread as a representative concavediffraction grating
monochromator.
Because a concave diffraction grating has both beam condensing and dispersing
functions, an optical system canbe configured with fewer mirrors.
In a spectrophotometer, use of fewer mirrors signifies a shorter optical
path,thus giving rise to an aberration-free bright optics.
For elimination of the aberrations which were essentially unavoidable in the
past, a stigmatic concave diffractiongrating has been developed by applying
Hitachi’s original technology. As a result, a higher resolution has been
realized.
A higher resolution has been achieved by eliminating coma
from the Seya- Namioka monochromator which is the most popular concave
diffraction grating monochromator. Its grooving is supported by the only ruling
engine in Japan. The diffraction gratings of Model U-2900/2910 have also been
made with this machine.
Spectral bandpass 1.5 nm satisfying European
Pharmacopoeia
European Pharmacopoeia requires a ratio of 1.5 or larger
when measuring 0.02% (V/V) solutions of toluene in hexane. In the spectrum at
right, a satisfactory value of 1.6 can be confirmed.
(Sample: 0.02% solution of toluene in n-hexane)
Personal computer-based instrument control and data
processing
U-2900 can be controlled by a PC equipped with optional UV
Solutions Program. UV Solutions Program provides not only basic functions such
as photometry quantitative analysis and wavelength scan but also the capability
of data handling as described below.
(U-2910 is the model exclusively for operation with a PC. A PC equipped with
Windows® is required for UV Solutions Program.)
Simple to
use
Buttons are
laid out so as to follow the operating procedure.
Hence, operations can be performed smoothly.
A rich
variety of data processing functions
Spectrum can be
expanded, contracted, smoothed, differentiated and integrated, and fundamental
arithmetic calculations are applicable between spectra.
Powerful
support for report generation
Measured data
can be sent to Microsoft® Excel®. One click of the Report button suffices for
data transmission.

ANALYSIS
OF CR(VI) IN TRIVALENT CHROMIUM COATING FILM BY THE DIPHENYLCARBAZIDE METHOD
WITH SOLID PHASE EXTRACTION |
|
In recent
years, use of a trivalent chromium coating film,which is low in toxicity and
complies with RoHS instructions, has entered mainstream use, in place of the
hexavalent chromium coating film which has been widely used as a finishing
agent. Measurement of the Cr(VI) contained in this corrosion protection
coating film may be accomplished by extraction with boiling water, followed
by application of a spectrometric method with 1,5-diphenylcarbazide. However,
a high sensitivity analysis is required for the quantification of trace
amounts of Cr(VI). |
