Roche Cedex HiRes Reference guide

Brand: Roche

Model: Cedex HiRes

Type: Reference guide

Roche Cedex HiRes is a high-resolution analyzer that can measure the size and concentration of particles in a sample. It is commonly used in quality control and manufacturing processes to ensure product quality and consistency. With its multi-sampler, the device can analyze up to 20 samples automatically, saving time and increasing efficiency. Additionally, the Cedex HiRes software allows users to modify data entry, change samples, and view results during the analysis process.

Working with the Multi Sampler — (April 2014)

Moving parts of the Multi Sampler may cause hand injuries. The Multi Sampler needle

may cause injuries during operation. Never use the Cedex HiRes Analyzer without the

protective cover in place for the Multi Sampler.

The Multi Sampler DefaultCup

The position of the Cedex Sample Cup used for the Prime, LM Shutdown, calibration and

cleaning routines is called the DefaultCup. An empty Cedex Sample Cup must be manually

placed in the position set for the DefaultCup before running LM Shutdown, focus adjustment,

Prime and all cleaning routines. This Cedex Sample Cup does not differ from the usual sample

cups. The standard (default) position for the DefaultCup is position 1 of the Multi Sample

Tray.

Using the Multi Sample Tray

To insert the tray, gently push the tray into the notch until the automatic tray rope starts

pulling it in. To eject the tray, gently push on the tray. The tray will be automatically ejected.

The tray can only be ejected when the system is idle. It cannot be ejected if the system is

moving or the needle is down in a cup.

Carrying out a Measurement with the Multi Sampler

Click on the MULTI RUN button on the Cedex Control Center to open the Multi Run

dialog box.

Fill 300 µL +/- 10% of the samples to be measured into individual Cedex Sample Cups

(maximum 20) and place them in the Multi Sample Tray according to the desired sequence.

Insert the tray into the Multi Sampler.

Click anywhere in the row of the Multi Run preparation area that

corresponds to the

location of a cup containing a sample. The row will be converted to edit mode, and the

sample and process parameters for the measurement can be deﬁned.

Enter the sample data and parameter information as described in the section “Carry out a

single measurement ” in the Quick Guide “Performing a Measurement ”.

Repeat steps 3 — 4 for the remaining samples to be measured.

Activate the status of each sample row by double clicking in the Status ﬁeld of the row to

be activated. The row appears pale blue, and further modiﬁcations of sample information is

impossible. Return to the Edit status by double clicking on the Status area of the sample

row to allow for further changes, if desired.

Alternatively, activate or deactivate all samples simultaneously by double clicking on the word

Status in the column heading at the top of the Multi Run preparation area. Conﬁrm the

safety query with YES to accept the modiﬁcation.

After some or all rows have been activated, click on the START button on the right-hand side

of the Multi Run dialog box to start the analysis of the activated measurements.

Modifying Data Entry, Changing Samples

Information about the operation and process parameters for samples that have not yet been

analyzed can be modiﬁed during the run as follows:

Double-click on the Status ﬁeld of the measurement to be modiﬁed. The status ﬁeld will

indicate that the sample is in edit mode.

Make desired changes to the measurement.

Double-click on the Status ﬁeld to re-activate the measurement

(status: active or scheduled).

Adding Measurements to the List while Measurements are Running

Sample rows in which data has not yet been entered can be ﬁlled out at any time while the

Multi Run is running. In addition, sample rows containing ﬁnished measurements (status:

done) can be cleared and prepared for a new measurement by double-clicking in the Status

ﬁeld of the row with the ﬁnished measurement. Sample data for a measurement cannot be

modiﬁed after that measurement has begun.

Viewing results via the Multi Run Result List

At the bottom of the Multi Run dialog box, the Analyzed Measurements ﬁeld displays the

list of results for measurements previously carried out. Measurements are listed in order of

process time, from the newest measurements at the top of the list to the oldest measurements at

the bottom. All measurements carried out using the Multi Run dialog box will be displayed in

this ﬁeld unless the Clear Resultlist button has been pressed, which will clear all measurement

results from the list.

In addition, measurements displayed in this ﬁeld can be restricted to only the measurements

carried out by the user logged into the system (mine), measurements that have not yet been

printed out (unprinted), and/or measurements carried out on that particular day (today).

Other results, such as Average Diameter, can be added for display in the result list via the User

Preferences (see “Adjusting Result Display in the Measurement List and Multi Run dialog boxes”

in the Cedex HiRes Operator’s Guide). Double-click on a measurement to view all results.

If the result list has been cleared, previously carried out measurements can still be viewed,

printed out and exported via the Measurement List dialog box (see “Using the Measurement

List” in the Cedex HiRes Operator’s Guide).
