Submitting samples via OALogin with a Sample Organizer, the vial position is assigned to a plate that is inside the Sample Manager - WKB10643

SYMPTOMS

• When submitting samples via OALogin with a Sample Organizer: OALogin directs you to a vial position that is inside the Sample Manager, instead of a free plate in the Sample Organizer
• This means that the Sample Manager door must be opened while it may be trying to inject and the plate is in an inaccessible position.
• It is confusing when the plate is not in the Sample Organizer. Is it missing or is it in the Sample Manager?
• Autosampler Pause is not disabled at OALogin Manager > Administration > Set Bed Layout
• Newer software (e.g. SCN 1049) shows the bug that was fixed in earlier versions (e.g. SCN 976)

ENVIRONMENT

• OALogin
• MassLynx 
• SQD2
• ACQUITY QDa Mass Detector
• SYNAPT XS
• Xevo TQD
• Xevo TQ Absolute
• Xevo TQ-S micro
• Xevo TQ-XS
• ACQUITY UPLC Sample Organizer

CAUSE

Software bugs occurs in several situations.
1. Bug in software causes MassLynx not to check the vial location or checks the location but still returns an incorrect location - CRI-8230

2. OALogin does not get a signal to check the current vial location:
2.1 OALogin uses Single Page Login—there is no step to trigger the Autosampler Pause stage,  so the system assigns the location to the last known good position, even if this is now in the Sample Manager.
2.2 The user logging in the samples has only one method they can use (assigned in the Group > Methods). Because the user does not select a method, the system does not receive a trigger signal.

FIX or WORKAROUND

1. Fix for bug
   CRI-8230 is fixed in SCN 1051 (667007867DD)
   (ACQUITY QDa, ACQUITY QDa II, RADIAN ASAP, SQ Detector 2, SYNAPT XS, Xevo G2 XS QTof, Xevo G3 QTof, Xevo TQ Absolute, Xevo TQD, Xevo TQ-GC, Xevo TQ-S, Xevo TQ-S cronos, Xevo TQ-S micro, Xevo TQ-XS) Instruments not listed as supported in SCN 1051 will not be fixed.
   
   Note: Was fixed in QDa in SCN 976 and subsequent software up to SCN 1048 (reported - might be earlier versions affected) but is broken again
2. Workaround for no check of vial location:
   2.1 Use only the OALogin Wizard to log in samples (not Single Page Login).
   2.2 Assign more than one method to each user (so user must select a method when logging in a sample), even if the second method is a duplicate of the first.
