1. 325
Dual Wavelength UV-Vis HPLC Detector
|
|
|
|
|
The
325 UV-Vis detector delivers superb sensitivity
and a wide,dynami c absorbance range. A
highly versatile instrument, the ProStar
325 incorporates easily into an existing
HPLC system or operates as a stand-alone
detector.
|
|
|
|
|
Simplicity
with Increased Productivity Dual pathlength flow
cells coupled with extended absorbance range dramatically
reduce the need for sample dilutions. Detection up to
40 absorbance units higher than most UV-Vis detec
tors.
Deuterium source for ultraviolet range and quartz halogen
lamp for the visible range.
|
|
|
|
|
Dual
pathlength flow cells for dynamic absorbance
range 40 times gre ater than conventional
detectors.
|
|
|
|
|
Scale-Up
Flexibility From analytical
to preparative flow rates, the ProStar 325 is quickly
configured with flow cells for scale-up work. Interchangeable,
cartridge-style flow cells handle microliter per minute
flow rates to hundreds of milliliters per minute.
|
|
|
|
|
Handheld
Computer Control Detection
parameters are quickly and comfortably downloaded
to the detector with the cordless, handheld
computer. Make wavelength changes, turn
the lamp on and off, or view chromatograms
right from your workstation chair.

335
HPLC Diode Array Detector
|
|
|
|
|
The
335 Diode Array Detector with programmable
slit widths delivers the highest sensitivity
and spectral resolution from 190
nm to 950 nm. The dual-beam optics and a
polychromator grating ensure greater accuracy
and reliability.
|
|
|
|
|
Built-in
versatility for microbore to preparative HPLC
The
ProStar 335 features dual pathlength flow cells, coupled
with two diode arrays. This significantly extends its
absorbance range capabilities compared to conventional
diode array detectors, making the ProStar 335 the only
true scale-up diode array detector on the market.
From
microbore to preparative flow rates, the ProStar 335
is quickly configured with flow cells for scale-up work.
Interchangeable, cartridge-style flow cells handle microliter
per minute flow rates to hundreds of milliliters per
minute.
Superior
sensitivity and spectral resolution Along
with programmable slit widths, Seamless Spectral Coverage
Technology* (SSCT) further supports greater sensitivity
and spectral resolution. SSCT eliminates second order
light to give the most accurate spectral information.
With
superb optical and spectral resolution, the ProStar
335 routinely provides detailed informa tion with even
trace amounts of analyte.

5. 355 Refractive Index Detector
|
|
|
|
|
The
Varian ProStar 355 refractive index (RI)
detector is engineered to be the most stable
and sensitive analytical RI detector in
the laboratory today. This universal detector
is ideal for the analysis of non-absorbing
compounds such as polymers, hydrocarbons,
carbohydrates, alcohols, and fatty acids.
The ProStar 355 detector has excellent thermal
stability and automated reference flushing
to meet the most demanding analytical
applications.
The
ProStar 355 combines low noise with active
flow cell temperature control to provide
a low drift baseline, resulting in outstanding
detection limits. Flow cell thermostating
eliminates 99.9% of the temperature effect
on the RI baseline.
|
|
|
|
|
Performance
Features
Digital
control of the optical zero makes it quick and easy
to zero.
Polarity
reversal is tied to the electronic autozero. When a
polarity change is made, the detec tor will automatically
adjust the baseline so that there is no baseline upset.
Automation
of optical and electronic autozero and reference flush
functions make the 355 an ideal detector for overnight
automated analysis.

363 Fluorescence Detector
|
|
|
|
|
Fluorescence
spectroscopy enjoys two distinct benefits
over UV-Vis spectroscopy-increased sensitivity
and enhanced selectivity. Sensitivity is
dramatically increased by looking for a
fluorescence signal against a dark background.
Selectivity is achieved by selecting both
the excitation and emission wavelengths
to screen out unwant ed interferences. Varian's
ProStar 363 Fluorescence Detector maximizes
sensitivity and selectivity to give you
total control over your analyses.
The
ProStar 363 provides the highest sensitivity
by using a continuous Xenon lamp. Continuous
lamps generate a significantly more stable
signal than flashlamps. Consequently, drift
and noise are dramatically reduced. The
unique optical design of the ProStar 363
permits simultaneous measurement of both
emission and excitation signals, thus accurately
correcting for lamp fluctuations. The combination
of the lamp and optics provide the quietest
signal possible, resulting in more reproduc ible
fluorescent measurements.
