3.0.21 (07-Dec-2009)

CHANGES

Acquisition

• Now allows 0.1s Averaging in FMS mode

FIXES

• PTOF Display bug fixed, first display was not working in v3019
• Nitrate Loading value fixed, displayed value had error in v3019
• Swap button bug fixed, Calibration Group and Sampling Type values were lost when swap was used in previous versions

3.0.19 (29-Sept-2009)

CHANGES

InfoVals

• InfoVal(106) indicates seconds after midnight at start of run
• InfoVal(107) indicates active menu number
• If DIO5, 6, or 7 is in, save state as save
• InfoVal(108, 109, 110) states of digital in 5, 6, 7 (NaN if disabled)
• InfoVal(111) Relative time within fast MS cycle (NaN if not FMS mode)
• InfoVal(112) Relative run number within FMS cycle (NaN if not FMS mode)

Menu Switching

• New menu value allows optional wait at the start of a run
• Added Menu Cycle Time Grid as alternative to run-based time grid

BitWise

• Baseline and SI area now based on MS mode; no longer need chopper to run Bitwise
• Single Ion peak list is now saved to menu file
• Optional "Bitwise on the hour" measures baseline and SI area every hour
• All three displayed nominal masses share a single peak discriminator, saved as menuVal
• Suggests best baseline bit, see: http://tof-ams.blogspot.com/2009/08/what-is-proper-baseline-bit-value.html

Acquisition / Acquisition Window

• Logic allows FMS with closed block = 0
• Logic allows MS mode with % Open = 100
• Added functionality and interface updates for MS acquisition without chopper (controlled with menu val 141)
• Zoom windows on right side of acquisition window allow change of nominal mass with scroll wheel
• If MSclosed does not exist, displayed resolution values are calculated from open data
• Option to display MSClosed sticks
• Horizontal zoom in stick display with mouse
• Eliminated %MSOpen. MS Dwell time now calculated as (MSOpenT+MSClosedT)*MSLoopsPerDwell. Loops enables multiple MSClosed / MSOpen *Dwells per dwell.
• Vertical scaling in zoom windows
• Check RealTime Configuration at load of window. See [| Related FAQ]
• PTOF DC markers calculation adjusted based on number of TOF/chop and co-adds
• Fixed display of speciated sticks for SP-AMS Dark Green for Cn and Fullerene
• MS Stick display size depends on what other modes are active in acquisition cycle

Digital Lines

• DIO5, 6, and 7 now configurable as in or out (common across menu)

If out, state unique to each menu If in, value is recorded and saved as infoVal

• Option to control acquisition start/stop from DIO5
• Option to control menu switching with encoding on 6 and 7

Mass Calibration Window

• Peak intensity displayed in units of Hz; calculation uses bit-ns per second, SI Area, and TOF pulser frequency
• Total Ion Current (TIC) reported below trace of peak areas/heights
• Option to save itx file with last acquired mass spectrum. Includes raw MS, raw mass axis, and unit mass resolution stick spectrum
• Added Accumulation mode as option on tuning tab. MS data are continuously acquired and summed, allowing determination of resolution (etc) for low intensity peaks.

Window Messages

• Allows control of acquire start/stop and menu number from external software with windows messages

Real Time Files / Serial Output

• Write MSSDiff.itx to C:\ToFAMS\ToFAMSData\LogFiles\TimeTrace\MS for each run. Optional - controlled by check box in Real Time box on averagin and saving tab.
• New Serial output formats

Front Panel

• If DAQ PC has internet connection, check for updated version of DAQ. If update exists, button on panel links to download.

National Instruments

• Auto-determination of National instrument board device numbers. If board(s) not found, features disabled accordingly.

3.0.3

CHANGES (Since 3.0.0)

Acquisition Window

• Optional automatic baseline and SI determination during acquisition. Turned on/off on AP240 tab of Menu Window. This is still considered a BETA feature. Last values are saved as InfoVals.

Calib Window

• Step sizes (volts) for TPS scans are saved as common menu values
• Scroll wheel and arrow keys to change TPS voltages and calibration center points

Info Vals

• If TPS remote control is enabled, last monitored TPS voltages are saved as infoVals for each run

Data Save

• Allows transient save in FMS mode. itx written to transient drive, without write to C: drive
