 |
| Excellent for
educational, quality control, and field applications, the SRI Model
210D is a complete, entry-level HPLC system in an economical package.
Everything you need is inside the compact, rugged chassis. |
|
|
|
|
| The 210D comes
standard with two detectors and a four channel
A/D board. The signal from the UV detector is on channel one,
and the Conductivity detector is on channel two. If you upgrade to
the six channel USB data system, there will
be four extra channels available for external detectors, which can
be easily connected to the customer access terminals on the left side
of the 210D. |
 |
|
|
|
The
UV detector is 254nm fixed wavelength. |
| This
chromatogram shows the analysis of a mix of Polycycylic Aromatic Hydrocarbons
by the UV detector in the Model 210D. |
|
| The
Conductivity detector is conveniently integrated into the body of
the low-volume UV cell. The entire detector compartment is thermostatted
to ensure the most stable possible baseline. It is particularly useful
for measuring anions, organic acids, and compounds which do not absorb
in the UV. |
|
|
20uL
of 1ppm chloride was injected into a 210D to obtain this chromatogram.
|
|
|
| The
Model 210D column heater will accept most HPLC columns up to 25cm
long. The heater is mounted on a vertical slide that conveniently
holds the heater above the compartment for column installation or
replacement. The temperature is adjustable from ambient to 100oC
for a wide range of temperature-sensitive applications. |
|
The
column heater may be raised from the operating position for easy
access.

The
solvent recycling valve is a huge convenience that saves time, money,
and disposal costs because it allows the user to recycle the solvent
when no peaks are eluting. The solvent recycling valve can also be
used as a single sample fraction collector. Using a PeakSimple
Event table, the solvent recycling valve can be switched at any
time during the analysis to divert the detector effluent from the
waste bottle to a sample vial when the peak of interest exits the
detector. |
| Use the PeakSimple
Event table to turn the solvent recycle valve ON at any time. |
|
| The
handy storage compartment built into the front of the 210D holds your
injection and priming syringes, spare parts, and a few vials securely
during shipping. No longer will you have to worry about your syringe
rolling off the bench onto the floor! Keep your HPLC tools with your
HPLC. |

Gradient
Upgrade
Unlike
other HPLC systems, the SRI Model 210D gradient upgrade can be performed
by the user, in the field, in about an hour. All the necessary wiring
is already included with the base isocratic system. All the upgrade
requires are just a few screws and plumbing connections to add the
second pump head and circuit board.
|
| |
|
|
| The
210D is completely field portable. The entire HPLC can run off the
12 volt power from the cigarette lighter in your vehicle. Whether
you are performing analyses in the jungle, desert, or city, the 210D
can go with you. It can be transported around the world in the rugged
re-usable shipping container, which is small enough to travel as airline
baggage. |
|
|
|
The
Model 210D is designed for easy one-person transport in the field.
