Cedex HiRes Analyzer Operator’s Guide

Step-by-step descriptions for performing measurements via the Measurement dialog box are provided in Section

B, Chapter 1, “Setting Up a Single Measurement in the Measurement Dialog Box”, in the Cedex HiRes Analyzer

User Training Guide.

For undiluted samples, enter a dilution factor of 1:1. A dilution of 1:2 refers to a mixture of one part cell

suspension and one part dilution medium. A dilution of 1:5 means that one part cell suspension has been

added to four parts dilution medium, etc. You may need to manually dilute samples with very high cell

densities (>1 × 10

cells/mL) prior to measuring.

The dilution ratio chosen from the list only relates to the manual dilution of the sample prior to placing the

sample on the system. Dilutions that are an automatic part of the measurement process in the Analyzer are

already taken into account by the Cedex HiRes Software; those calculations are automatically performed and

are not related to entered dilutions.

The Sample Port area indicates which type of sample port should be used for the measurement, based on the

instrument conﬁguration (see the Cedex HiRes Analyzer Operator’s Guide for more information):

c Multi Sampler: use the Multi Sample Tray.

c Single Port: use the single sample port.

c Remote Port: use the Remote Sample Port located at the top of the instrument (see Chapter A, Figure 1).

c Custom Port: Consult with your Cedex administrator for more information about which sample port to

use before running any measurements.

2.3 Interrupting a Measurement

An orange EMERGENCY STOP button is located on the left-hand side of the Measurement dialog box and

can be activated during the measuring procedure to interrupt the analysis process. If the EMERGENCY STOP

button is selected, a message appears asking, “Do you want to cancel the process?” Select YES to stop and abort

the process immediately. Select NO to put the process on hold.

If YES is selected, the EMERGENCY STOP button changes to read UNLOCK QUEUE. Before more measure-

ments can be run, the system must be unlocked by clicking on this button. If NO is selected, the EMERGENCY

STOP button changes to RESUME. Click on RESUME to resume the measurement process.

Only use the EMERGENCY STOP button in an emergency. Actual measurement data may be lost.
