Empower: What are the conversion units from "mV" to "DelRIU" in Empower when using a 2414 detector? - WKB55790

ENVIRONMENT

• Empower
• 2414 detector
• RIU/V units

ANSWER

Refer to the following table found in the Operating in RIU mode section of the 2414 Refractive Index Detector Operator's Guide.

410 mode and RIU mode conversion factors and equivalencies:

Sensitivity   Maximum output (V)    RIU/V
  1                 1                                5.00X10-3
  2                 2                                2.50X10-3
  4                 2                                1.25X10-3
  8                 2                                6.25X10-4
 16                2                                3.12X10-4
 32                2                                1.56X10-4
 64                2                                7.81X10-5
128               2                                3.91X10-5
256               2                                1.95X10-5
512               2                                9.77X10-6
1024             2                                4.88X10-6

Calculate Delta RIU from a Millennium result table, as follows:

Empower, Millennium32 and higher:

Delta RIU = peak height (volts) / (200) (sens)

ADDITIONAL INFORMATION

22Nov2024: This conversion is the same as listed in wkb18430. 1000 was used for unit conversion.

RIU = mV/ (200 x1000 x Sensitivity)
