Dear community,
After Tuesday's PSI MSS WG teleconference and following the notes sent
by Eric on 29th, we agreed some concrete points (if I'm wrong in any of
them, please, correct me):
- Adding three new terms: "electrospray supply type", "static supply
electrospray" and "fed supply electrospray", descending from source.
- Making obsolete the term "paul ion trap" (MS:1000297).
- Put axial and redial ejection linear ion traps under linear ion traps
A detailed description of the changes is at the end of this message.
Related tasks to this changes are:
- Pierre-Alain will find an MS guru at Bruker to clarify
- Need to update mapping files to accommodate "electrospray supply
type", "static supply electrospray" and "fed supply electrospray"
If you think this is correct, or not incorrect, I'll update the
controlled vocabulary in three working days: (Tuesday).
In a couple of hours I'll send another email collecting the remaining
discussion points related to the controlled vocabulary.
ADDITIONS
================
Add three terms to accommodate de MIAPE concept of "Supply type".
[Term]
id: MS:1001914
name: electrospray supply type
def: "Whether the sprayer is fed or is loaded with sample once." [PSI:MS]
relationship: part_of MS:1000458 ! source
[Term]
id: MS:1001915
name: static supply electrospray
def: "The sprayer is loaded with sample once." [PSI:MS]
is_a: MS:1001914 ! electrospray supply type
[Term]
id: MS:1001916
name: fed supply electrospray
def: "The sprayer is continuously fed with sample." [PSI:MS]
is_a: MS:1001914 ! electrospray supply type
CHANGES
================
CHANGE 1-> Paul ion trap is now obsolete, because redundant to
quadrupole ion trap
[Term]
id: MS:1000297
name: paul ion trap
def: "OBSOLETE A device that permits the trapping of ions by means of an
alternating current voltage. The ejection of ions with a m/z less than a
prescribed value and retention of those with higher mass depends on the
application of radio frequency voltages between a ring electrode and two
end-cap electrodes to confine the ions in a circular path. The choice of
these voltages determines the m/z below which ions are ejected." [PSI:MS]
comment: This term was made obsolete because it is redundant to
quadrupole ion trap
synonym: "quadrupole ion trap" RELATED []
is_a: MS:1000479 ! purgatory
is_obsolete: true
CHANGE 2-> Axial and redial ejection linear ion traps under linear ion traps
[Term]
id: MS:1000078
name: axial ejection linear ion trap
def: "A linear ion trap mass spectrometer where ions are ejected along
the axis of the analyzer." [PSI:MS]
is_a: MS:1000291 ! linear ion trap
[Term]
id: MS:1000083
name: radial ejection linear ion trap
def: "A linear ion trap mass spectrometer where ions are ejected along
the radius of the analyzer." [PSI:MS]
is_a: MS:1000291 ! linear ion trap
