Biotage ELSD-1080
10. Turn on the source gas to a pressure of about 60-100 psi.
11. Switch on the Biotage ELSD-1080 detector, and select a
desired method (e.g. Method “XXX”).
12. Initiate heating by selecting RUN mode using the arrow
keys on the front keypad.
13. When the unit has reached temperature, the baseline noise
should be checked to ensure that it is < 0.2mV peak-peak.
This verifies that the gas supply is clean and dry.
14. If the baseline is within the limits, auto-zero the
detector.
15. Turn on the eluent flow and allow the system to
stabilize.
16. Again check the baseline noise. It should not have
increased significantly and should be
≤ 0.5mV. Typically
pure water should give no more than 0.4mV peak-peak,
while pure organic solvents should be less than 0.3mV.
If the baseline noise is excessive, then please refer to
the troubleshooting Section in Chapter 5. Where noise
and all other conditions are acceptable, the detector is
ready to begin work.
Note: Some volatile buffers can generate considerable offsets and
increased noise levels.
2.8 Connecting the Detector to Your PC
To operate the Biotage ELSD-1080 detector, a free Serial (RS-
232) communications port (1 to 255) is required on your PC.
Most computers are supplied with at least one serial port as
standard, but if your PC does not provide a serial port or you
are already using the existing serial ports for other devices,
then there are a couple of options available to you:
1. Use a Universal Serial Bus Interface (USB)
If your PC has one or more Universal Serial Bus (USB)
connectors then you can use a “USB – Serial Port Adaptor”
(Part No. ELSD-0860-0620), which provides a Serial Port
connection to your PC. The Universal Serial Bus interface is
supported on:
f
Windows 2000
f
Windows XP
Note: USB is NOT Supported on NT 4.0. You may require extra
software to use USB on Windows
2. Adding an Extra Serial Card to your PC - Using Multiple
Serial Ports
Multiple Port Serial cards are available, which allow 4, 8 and 16
extra serial ports to be added to your PC using a single PCI
card.
Ensure that the ELSD-1080 is switched on and operating
normally. Make sure you have one free and valid RS-232
communications port (1 to 255).
