Cylinder Management

A good QA program has many elements, including but not limited to reviewing your data on a periodic basis, managing cylinder data, and recording Performance Specification (PS) testing information. One of the new features in StackVision Version 6.2 is Cylinder Management, which replaces Cal Gas Management. Our new tool is an integral part of how StackVision helps collect and prepare the compliance portion of your QA program.

Cylinder Management can be found in the New Client Menu:


Cylinder Management allows you to manage gas cylinders that are used to run calibrations and validations for daily, weekly, quarterly, and annual QA tests (e.g., linearities, NOx correlations, RATAs). The Cylinder Management interface now shows all cylinder related information on one screen and allows you to assign them to calibration and validation phases. It provides visual cues as well as alarm capabilities to warn you when a cylinder is close to expiring. Reference values can be downloaded easily to the data controller, eliminating the need to update them in two places. The colors in Cylinder Management identify the state of your cylinders and phases, as well as provide visual cues to help manage your calibrations and validations. A screenshot of the Cylinder Management interface is shown in Figure 2 below.




What Do the Colors Mean?

When a cylinder is ready to use, it will have white shading which will turn gray when selected. At the same time, on the Phases section, phases corresponding to the selected cylinders will turn green (as shown in Figure 2 above). To link the cylinder to the phase, click the green highlighted phase. If the cylinder can be used on multiple phases, each of those phases will be shaded green. Clicking on the green highlighted phases will link the cylinder to those phases. If phase is selected, corresponding cylinders will be highlighted green. These visual cues are summarized in Figure 3 below.



Using Filtering Options:

Filters can be applied individually to the Cylinders section and Phases section. These filters enable users to show/hide or include/exclude cylinders and phases. Filters can also be used to control the level of detail to be displayed.



 

Adding or Editing Cylinders: Adding_cylinders.png or Editing_Cylinders.png
 
Click the Add button at the top left of the Cylinders pane to open the Add Cylinder window or click the small pencil icon in the top right corner of a cylinder object and select Edit to open the Edit Cylinder window.

The Add Cylinder and Edit Cylinder windows include the same cylinder details. These fields are displayed in Figure 5 to the right. If you are editing a cylinder that is linked to one or more phases, some additional options are available, and some fields are locked (grayed out).

Cylinder ID: Enter the vendor-assigned identification or serial number found on the cylinder associated with the protocol gas certificate.

Name: Enter a descriptive name for the cylinder. This name will help distinguish each cylinder in the Cylinders list (see example below). If you do not enter a name here, the cylinder ID is displayed as the cylinder name.
 

Expiration Date: Enter the date that the cylinder expires. You can type it manually, or you can select a date from the calendar pop-up to the right of the field.

Alarm: Check the Enabled option to set a system alarm that is triggered when the cylinder’s expiration date is approaching. In the Warning Days field, enter the number of days ahead of the expiration date that the system triggers the alarm.

Vendor: Select the cylinder vendor from the drop-down list. If you need to add a new vendor, click the add button Add-button.png to the right of this field. If you add a new vendor, it is added to the list of cylinder vendors in StackStudio after you save your updates in Cylinder Management.

Document: Use this field to attach documents such as cylinder certificates and specifications. Click the ellipsis button Ellispses-Button.png to the right of this field to browse for a document. The file should already be available in your network (i.e., scanned in or created and saved at a previous time) to use this method to link it to the cylinder.

Order Date, Receive Date, and Ship Date: Use these fields to indicate the date the cylinder was ordered, received, and shipped.

Location/Comment: Use this field to type any notes about the cylinder, such as its location in your facility.


Gases: Use this section to define the gases contained in the cylinder. Click the ellipsis button Ellispses-Button-(1).png to the left of the Gases field to open the Cylinder Gases pop-up window shown in the example below. Check the boxes for the gases contained in the cylinder and enter the reference values in the field to the right of each gas. Use the drop-down lists to the right of the reference values to select the gas unit of measure (%, PPM, etc.):

PGVP Gas Combination: Use this field to select the PGVP gas combination that is associated with the cylinder. This is the area of Cylinder Management where you will manage all of your protocol gas information.


Most of the PGVP information is added in the previous section, Expiration data, Cylinder ID, Vendor Id, etc. Click on the ellipsis Ellispses-Button-(2).png at the bottom of the Cylinder tab and check the gas combinations in the cylinder. If the gas type is not available, use the Customize option to add the required gas(es).

Importing Cylinder Information  Importing-(1).png

Beginning in SV 6.0, Cylinder Management, as well as the older Cal Gas Management tool, supports Importing or Scanning of Red Ball Smartcert QR Codes and ESC's CEMSGAS Schema.

Clicking Import in the Cylinders toolbar of Cylinder Management opens the Import Cylinders dialog. Use this dialog box and any of the following options to import cylinder data:

Scan: Use a QR Code reader to scan the QR code found on the Certificate of Analysis. Cylinder Management supports QR codes for the following: Airgas®, Red Ball Smart-Cert, and any QR code that uses ESC’s CEMSGAS schema (template). You can either scan QR Codes directly into Cylinder Management, or scan QR Codes to a file for importing later.

Paste: Cylinder data previously copied to the Windows clipboard can then be pasted in the Import Cylinders dialog box.

Import: Import a spreadsheet or text file. Supported file types include .xlsx, .xls, .csv, and .txt.

The imported data will create a cylinder noted with an i-icon-01.png. Clicking this icon will display cylinder details. Based on the data being imported, the cylinder tile may also include a label to indicate issues with the imported data. For example, if the data you are currently importing is a duplicate of a cylinder already in Cylinder Management (such as a duplicate of a cylinder ID that has previously been deleted), the system adds a cylinder tile labeled “Duplicate” in the Import Cylinders dialog box. See the example above. Because Cylinder Management does not support duplicate cylinder IDs, the duplicated cylinder is not imported.

The following table (Figure 9) shows information about the types of labels that may display on cylinder tiles based on the data being imported.

Editing Cylinder Information:

If you open the Edit Cylinder window and see that some fields are locked against editing, you will need to unlink that cylinder from any phases before you can edit those fields. The Unlink Helper button is available at the top right of the Edit Cylinder window to assist you with unlinking cylinders (see Figure 10).

When you click the Unlink Helper button, you can then use the Unlink Cylinder pop-up window to step you through your options when unlinking the cylinder:

 

Editing Phases:

All available phases are displayed in the Phases pane.  Phases cannot be created through the Cylinder Management tool. They must be added in StackStudio, and they will then be available in Cylinder Management. To add a phase, use the following editor in StackStudio: StackStudio > Data Controllers > Calibrations > Sequences.

If you need to edit a phase in Cylinder Management, click the small pencil icon in the top right corner of the phase object (Figure 11) and select Edit Phase Settings.


As shown in Figure 12 below, the Edit Phase Settings window allows you to view and edit the phase's gas levels:


If the Percentages column is set to Part 75, the tool automatically sets the standard low and high limits for each gas type and gas level.

If you want to enter your own gas levels, select Custom (as shown in Figure 13 below) in the Percentages column, and define the gas values.


If you make any changes, use the buttons at the top left of the window to save and upload the changes to the data controller.


 

Linking Phases and Cylinders:

To assign or link a cylinder to a phase, start by clicking on the cylinder. The active cylinder background will change to a dark gray color and corresponding phases background color will change to a green color. Click on the phase to link the cylinder and the phase.



Once a cylinder and phase are linked, the cylinder will display a small blue box with the total number of phases the cylinder is linked to.


The phase, as shown in Figure 17, will display cylinder information and link icon on the cylinder information section indicating an active link to a cylinder.


Click the link icon in Figure 18 to display cylinder information and Unlink options.
