Save Hanchar-Montel Geochron Calculations

This menu will output Pb, Th and U concentrations (in PPM), Rel% Error (in percent) and Detection Limits (in PPM) for use with John Hanchar’s monazite calculation spreadsheet. The format is as follows:

 

SAMPLE      Sample name (in double quotes)

LINE        Line number

El Conc Pb  Elemental weight percent Pb (in PPM)

Rel% Err Pb Relative analytical error Pb (in percent)

CDL Pb      Elemental detection limit Pb (in PPM)

El Conc Th  Elemental weight percent Th (in PPM)

Rel% Err Th Relative analytical error Th (in percent)

CDL Th      Elemental detection limit TH (in PPM)

El Conc U   Elemental weight percent U (in PPM)

Rel% Err U  Relative analytical error U (in percent)

CDL Pb      Elemental detection limit U (in PPM)

TOTAL       Total weight percent

DAT/TIM     Acquisition date and time in system defined format

X-POS       X stage position

Y-POS       Y stage position

Z-POS       Z stage position

RELDIST     Relative distance (in microns)

BEAMCUR     Beam or probe current (in nA) (array if combined conditions sample)

ABSBCUR     Sample or absorbed current (in nA)

El ONTIM Pb On-peak counting time

El HITIM Pb High off-peak counting time

El LOTIM Pb Low off-peak counting time

El ONTIM Th On-peak counting time

El HITIM Th High off-peak counting time

El LOTIM Th Low off-peak counting time

El ONTIM U  On-peak counting time

El HITIM U  High off-peak counting time

El LOTIM U  Low off-peak counting time

 

Note that the total number of lines output will be stored before the first line data output. Samples that do not contain all three elements will be skipped and a warning will be logged to the log window.
