Your need, to my point of view, the survice engineer of Shimadzu Labsolutions could give you the idea. I rearly use Shimadzu instrument recently. It depends on softwere program of each brand and version. I apologize for not being able to answer this question.

Here’s how you can streamline your data processing and exporting in Shimadzu LabSolutions Version 5.71 SP1: 1. Removing Unwanted Peaks in Bulk ✅ Set a Global Data Processing Method Instead of manually removing peaks each time, create a processing method that defines peak integration parameters: Go to "Data Analysis" → "Processing Method" → "Integration Settings." Set retention time limits to exclude peaks below 4.5 minutes. Save the processing method and apply it to all 40 data files in one go using the "Batch Reprocessing" feature. ✅ Use "Batch Processing" to Apply the Method: Open "Batch Processing" in LabSolutions. Load all 40 files. Apply the processing method to all at once, which will automatically remove unwanted peaks based on your set criteria. --- 2. Bulk Export of Data ✅ Export All Data Files at Once (ASCII/CSV): In LabSolutions: Go to "Batch Processing." After reprocessing, select "Export All" under the "File" menu. Select output format as ASCII or CSV. All files will be exported simultaneously. ✅ Automate Export to Excel: If you want to automate data handling in Excel: Export to CSV format. Use Excel's Power Query to load all CSV files into one workbook for easy processing. --- 3. Bulk Export of Chromatograms ✅ Export All Chromatograms as PDF/Images: In LabSolutions: Go to "Batch Processing" Select all files Export chromatograms as PDF or image files in one go using the "Export" function. You can choose the output folder and format (PNG, JPEG, or PDF).

Hi, thank you for your replies. I couldn't find the "Processing Method" and "Batch Processing" that you mentioned. Where do you find them?

In Shimadzu LabSolutions Version 5.71 SP1, the terms "Processing Method" and "Batch Processing" may not appear explicitly in the menu, but the equivalent functions exist under Postrun Analysis and Data Analysis. Here’s where to find them:

1. Removing Unwanted Peaks in Bulk

Since LabSolutions doesn’t have a direct "Batch Processing" function, you can apply "Data Analysis Method" to multiple files:

1. Open LabSolutions Postrun

Go to [Postrun] in the software.

2. Set Up a Data Processing Method to Remove Unwanted Peaks

Open one chromatogram.

Click "PDA Data Processing" or "Quantitative Processing" (depending on your setup).

Go to "Peak Integration" and adjust parameters:

Set a retention time filter to only integrate peaks at 4.5, 6.5, and 11 min.

Save this as a New Processing Method.

3. Apply the Method to All Files at Once

In Postrun, go to File → Batch Processing Settings (or "Batch Recalculation" in some versions).

Select all 40 files and apply your saved processing method.

This will automatically remove unwanted peaks across all files.

2. Bulk Export of Peak Table Data

LabSolutions does not allow exporting peak tables in bulk directly, but you can automate it:

1. Export Peak Table in ASCII Format (For Each File):

Open [Postrun] → [Peak Table].

Click "Export" → Choose ASCII (.txt) or CSV (.csv) format.

This needs to be done per file, but you can automate it with a script in Excel.

2. Automate Bulk Data Import into Excel:

Save all ASCII/CSV files in one folder.

In Excel, use Power Query (Data → Get Data → From Folder) to import all CSV files into one sheet for further processing.

---

3. Bulk Export of Chromatograms

1. Export Multiple Chromatograms as Images/PDF at Once:

In Postrun Analysis, go to File → Export Chromatograms.

Select multiple files.

Choose output format (PDF, PNG, JPEG).

If this menu is not available, another workaround is to use "Batch Printing":

Go to Postrun → Print → Batch Print and save as PDFs instead of printing.

Thank you for your further clarification.

Unfortunately I could not find the Batch processing and I could only select one file at a time using the software.

It only allows me to export each chromatogram one by one in ASCII format as instead of pdf/images.

Anyway, I found a way to export ASCII to a folder whenever it complete the analysis of a sample by changing the setting in Realtime Batch. However, it only shows the the data from Peak Table 1 at 210nm, but I want is actually the data from Peak Table 4 at 254nm. Is there any way (1) to edit my HPLC runs so that the first peak table refers to data at 254nm specifically, or (2) edit the ASCII data export setting so as to include the 254nm data?

Currently, I have to edit the Method View - Compound Table in each raw .lcd data individually. It automatically showed 6 Targets, but I would like to define my own targets and internal standard. Is there anyway to edit the Compound Table once and for all?

Thank you.

You need to apply your integration parameters to the method that is used for the batch run (not retroactive). I use the Postrun Data Analysis section for this. Open LabSolutions, navigate to the Postrun tab and select Postrun. Open one of you chromatograph files using the folder directory. Then in the integration tab (bottom right), click on the Program icon. This will open a window wherein you can set various integration parameters, including turning off integration between specific residence times. You'll then save these parameters to the method (sorry I can't remember if you are prompted to update method once you leave the integration window or if you have to save manually). These integration parameters will be utilized the next time you use this method in a batch run.

Oh yeah one more thing, you can apply these new method parameters to each chromatograph file (one by one unfortunately) by clicking File > Update Quantitation Parameters (or something like that, I can't remember the exact term). Here is a decent video tutorial of using Postrun data analysis. https://www.youtube.com/watch?v=1QjEMWYi5ec
