Analysis proceeds without warning when there is a mismatch between instrument method and configured instrument stack - WKB100856
SYMPTOMS
- Mismatch between instrument method and configured instrument stack
- Analysis proceeds without warning
ENVIRONMENT
- Empower
- ACQUITY
- ACQUITY Console
CAUSE
This behavior is as designed.
Empower allows flexibility to operate in various regulated and non-regulated environments. Empower allows methods to be used that contain additional configured modules.
The driver/ICS does not provide commands for modules that are not included in a method but are configured in the console.
In this case the method does not contain a CM and was run on an instrument with a CM configured.
In a regulated environment, this system flexibility allows organizations to run multiple methods on a single system. (Appropriate change controls should be in place to avoid unintended changes in configuration or use. Many changes that can be made to a system are not identifiable by software, so external change controls are required.
FIX or WORKAROUND
- Name methods to describe the configuration to which they pertain.
- Put necessary controls in place to confirm prior to running that the method matches the console.
ADDITIONAL INFORMATION
An enhancement request (CRI-2181) was raised requesting an informational message be displayed when there is a mismatch between instrument method and configured instrument stack.
