When you want to use JASCO-HPLC, please turn on the following apparatus.
UV detector

Pump for Eluent APump for Eluent B



Mixer



Degassor (Sorry, the photo doesn’t show the picture of it totally…)

Mobile Phase MixerAuto-sampler (when you want to carry out automatic measurement)

Then, please double-click “ChromNav” icon and start “ChromNav”.
Log-in ID and password is same: “gousei”.

3There are 5 icons:

解析モードで起動: for Analysis Mode

HPLC_E-L-AS-SYSTEM: use HPLC-E with auto-sampler (automatic measurement)

HPLC_F-R-AS-SYSTEM: use HPLC-F with auto-sampler (automatic measurement)

HPLC-E-L-MANUAL-SYSTEM: use HPLC-E (manual measurement)

HPLC-F-R-MANUAL-SYSTEM: use HPLC-F (manual measurement)

Please double-click the suitable icon and choose the project you need.

4

If it is your first time to use this apparatus, please create your own project newly as follows.

5B) For Manual Measurement
For manual measurement, you first need to set the view mode as “マニュアル測定”.

6

(1) Making Control Method
You can set the measurement details by setting “Control Method”.

Following 3 boxes should be checked:

ポンプ: PU-2080

UV 検出器 #1: 指定しないバルブ/イベント*: 指定しない*The reason this box should be checked is not clear; the supplier checked this box at explanatory meeting.

7”ポンプ” tab … you can set the mobile phase gradient.
In following figure, standard gradient setting for measurement is shown.

(Eluent A: aqueous TFA (0.1%), Eluent B: MeCN)

You also need to set the washing method; please fill each box with following values.
initial condition → A: 0%, B: 100%; other values should not be changed

eluent gradient details → don’t fill in anything

analysis time → 20.0 min”UV #1” tab … you can set the wave length for measurement.
You can set the wave length from 190nm.

Finally, please save your method with appropriate name and close this window.
(ex. “0-100_40min_1mLmin_230nm” or “wash_MeCN_1mLmin”)”バルブ/イベント” tab … you don’t need to do anything.

8(2) Preparation for Measurement

At first, you need to wash the column with MeCN. Washing takes 10 minutes usually.
Please select washing method you set before and start washing as follows.

9During washing, it is recommended to set the measurement information as follows.
シーケンス名 → today’s date

クロマトグラム名 → experiment number

コントロールメソッド → select the control method for analysis

取込時間(min) → −0.5 min from the analysis time of the selected control method

注入量(L) → injection volume10

After 10 minutes, please start pre-run as follows. Pre-run takes 10 minutes usually.

11

(3) Measurement
After 10 minutes, please inject your sample with 50 μL syringe from injection port as follows.
The measurement starts automatically when the following process is carried out.

You can see the measurement proceeding in “クロマトグラムモニター”.

121.

inserting syringe

2.

“INJECT” → “LOAD”

3.

injecting sample

4.

“LOAD” → “INJECT”

5.

extracting syringe(4) After Measurement
When the measurement is finished, the display changes from “Run” to “Run/Wait” and Eluent A is flowed.
As acidic solution has bad effect on column, you are recommended to fill column with MeCN.

Please click the “STOP” icon and click the “MONIT” icon and select wash method.
Solvent changing will take 10 minutes.

After 10 minutes, you can stop the washing.

13C) For Automatic Measurement Using Auto-Sampler
For manual measurement, you first need to set the view mode as “測定シーケンス”.

14(1) Making Control Method
You can set the measurement details by setting “Control Method”.

Following 4 boxes should be checked:
オートサンプラー: auto-sampler

ポンプ: pump

UV 検出器 #1: UV detector No. 1

バルブ/イベント**The reason this box should be checked is not clear; the supplier checked this box at explanatory meeting.

“オートサンプラー” tab … you don’t need to do anything.

15”ポンプ” tab … you can set the mobile phase gradient.
In following figure, standard gradient setting for measurement is shown.

(Eluent A: aqueous TFA (0.1%), Eluent B: MeCN)

In order to carry out a measurement sequentially, initializing time (8 min, eluent A 100%) is set.

16

Also, you are recommended to set pre- and post-sequence washing method.

<pre-sequence><post-sequence>

17

”UV #1” tab … you can set the wave length for measurement.
You can set the wave length from 190nm.

Finally, please save your method with appropriate name and close this window.
(ex. “AS_0-100_40min_1mLmin_230nm” or “AS_wash-start_1mLmin” or “AS_wash-end_1mLmin”)”バルブ/イベント” tab … you don’t need to do anything.

18

(2) Preparation for Measurement

You need to set batch table for automatic measurement.
Following 6 blanks should be filled as follows:タイプ: UNK

サンプル#: vial port number you used

注入量: injection volume, μL order

クロマトグラム名: experiment number

取込時間: −0.5 min from the analysis time of the selected control method

コントロールメソッド: appropriate control method

サンプル名: experiment number

You are recommended to add “wash-start” line before your first sample and add “wash-end” line after
your last sample, as shown in above.

19

Please don’t forget to set “end mode” as follows:

When you finish setting the batch table, please save it. As for the filename, date will be suitable.

20(3) Measurement & After Measurement

Please open the batch table you have set.

Further sample addition and sample delete can be done.
When the change is finished, please don’t forget to save batch table.

Please don’t forget to set the injection port position as “LOAD”. When measurement is carried out with“INJECT” position, data won’t be saved.

21

Automatic measurement starts when you click “START” icon.

You can see measurement proceeding in “クロマトグラムモニター” tab.

22

When the measurement is finished, you will see the following view.

Please go to the analysis mode (p. 25~).

23D) For Overnight Measurement
For overnight measurement, you need to use auto-sampler.
However, if you carry out overnight measurement in your own account, other person who also wants to carryout overnight measurement can’t add his/her sample and conduct his/her measurement.
Therefore, for overnight measurement, please use the common account named “overnight”.
In account named “overnight”, there are following 4 common control methods:
0-100_40min_230nm (flow: 1 mL/min)0-100_40min_301nm (flow: 1 mL/min)

0-100_40min_254nm (flow: 1 mL/min)

wash_230nm (flow: 1 mL/min, MeCN 100%)

Please use these methods as much as you can in order not to increase unnecessary methods.

Other setting details are the same as shown in section C (automatic measurement using auto-sampler).
