4.3 Defining Sample

4.3.1 Without Sample Table

When “Use Sample Table” is avoided in Analysis Method, samples must be defined in the following procedure before measurement.

(1) Click the button. A window as shown in Fig. 4-27 will

appear.

Fig. 4-27

(2) Enter the sample name and comment.

Maximum enterable characters (half-size)

Sample name : 40 characters Comment : 255 characters

For automatic saving, put a check mark for “Auto File” and specify a file name. Click the Select button, and then specify a saving location and enter a file name. When a check mark is put for “Auto File” and for “Auto Text file” or “Auto Meta file,” a photometric data file can automatically be saved in the following file format.

4.3.1

 ASCII Text Files (*.txt)  Graph Meta Files (*.wmf)

The file will be saved in the name specified for “File name.”

(3) After entry, click OK.

4.3.2 With Sample Table

When “Use Sample Table” is selected in Analysis Method, samples must be defined in the following procedure before measurement. (With the U-5100, a sample table is also settable under the condition that “6 Cell Mode” and “6 cell control mode” are both activated on the General tab page. In this case, the maximum number of samples is limited to 5. The set number of samples will automatically be measured.) Open the monitor window and click the (Edit Sample Table) button. When a sample table window as shown in Fig. 4-28 is displayed, you should input each name and comment of samples to be measured.

(1) For creating a sample table newly, enter the number of samples and click the Update button. For example, when there are 5 samples, enter “5” for Number of Samples and click the Update button.

Fig. 4-28 Sample Table

When a sample table has already been created, a confirmation message such as “Changing the number of sample entries will clear all existing records. Are you sure you want to continue?” will be displayed.

Yes : A sample table for the specified number of samples will be created newly. No : Execution will be stopped.

(2) For adding a row after the last row of the present sample table, click the Insert button.

(3) For deleting an unnecessary row as shown in Fig. 4-29, click

the No. cell of that row to make it active. Then, click the Delete button.

Fig. 4-29

The active row will be deleted.

(4) Sample name and comment of each sample can be directly input by clicking the respective columns.

Maximum enterable characters (half-size)

Name : 40 characters Comments : 255 characters

For the U-5100, the function for auto zero before sequence is provided. When the check box for this function is turned on, auto zero will automatically be carried out with cell A before sample measurement. After the auto zero operation, sample measurement is carried out. Unless the check box is turned on, sample measurement starts without auto zero operation. Therefore, auto zero operation is always required before start of measurement.

U-5100

(5) Collective Input of Sample Names

Sample names of Common Sample Name + Start No., Common Sample Name + (Start No. + 1), … can collectively

be entered in the following procedure.

(a) Enter a common sample name for “Common name.”

A maximum of 36 half-size characters can be entered. (Example: SampleA)

(b) Apply a check mark to “Auto Numbering” and enter a start No. (Example: Start No. = 1)

4.3 Defining Sample

(c) Select the first row for collective input of sample names by clicking “No.” in this sample table. Plural rows are selectable by clicking the numbers for sample name setting with the Ctrl key held down.

Fig. 4-32

(d) Then, click the [Input] key, and the sample names of Common Sample Name + Start No., Common Sample Name + (Start No. + 1), … will be entered. (Sample names of stdA001 to stdA005 shown in Fig. 4-33 will be entered.) If you click the [Input] key without applying a check mark for Auto Numbering, the common sample name will be entered for active row.

(6) Specify a data file saving folder.

For specifying a data file saving folder, implement the following procedure.

(a) When this folder has already been saved, you should display the “Browse for Folder” dialog box by clicking the Browse button. After folder selection, click the OK button.

(b) For creating a folder newly, carry out the following

procedure.

1) Display the “Browse for Folder” dialog box as shown in Fig. 4-35 by clicking the Browse button. Specify a path for folder creation.

2) Click the Create Folder button to display the “Create New Folder” dialog box as shown in Fig. 4-36. Enter a folder name for “Name” and click the OK button. Maximum enterable characters (half size):

20 characters

A folder of the specified name will be created under “Current folder.”

(7) Enter a file name. (Example: test1)

Maximum enterable characters (half size): 40 characters

Data file will be saved in the name “File name.udq” into the file saving folder. (Example: test1.udq) When a file of the same name as entered here has already been created, your data file will be saved in “data file name + measurement date.” (Example: test1_20100811164856.udq) In case of the measurement in which a concentration correction coefficient need not be entered, check your entries, and then click the OK button. This is the end of sample table setting. For entering a concentration correction coefficient, go to step (8).

(8) A concentration correction coefficient can be entered. For this purpose, proceed as follows.

(a) Put a check mark for Conc correction.

8 (a)

(b) A concentration correction coefficient table is now displayed as shown in Fig. 4-38. Each value of Weight, Solvent, Dilution and Correction factor is listed. Click a column cell for change and enter your value directly there. For each item, entry is allowed within 0.000001 to 999999 and in up to 6 significant digits.

8 (b)
