Improvements to detector technology results in higher
sensitivity in both the EA1000A-III and EA1000VX.
This means improved count rate, resolution, and speed.

Time to fall below Cd 20 mg/kg; Pb, Hg, Br, Cr 100 mg/kg at 3σ standard error
Improvements in analyzer components and configuration
allow the new Hitachi EA Series to rapidly increase
the number of samples that can be processed
Products Standby time/seconds
SEA 1000A-ll 75
Improved efficiency by reducing system standby time when
starting a measurement and processing software
Compares total standby time for three measurement conditions
What is meant by standby time?
It is the time between each measurement to change the
measurement condition (analyzer configuration) for optimized results
So…faster standby time means faster throughput
Innovative precision control software stops the
measurement when target precision is achieved.
Benefit / Advantage
- Greater throughput with most efficient measurement time
-Do NOT need to set measurement time for each run
- Achieve good data without a specialized operator

Software automatically finds overlapping element peaks and
selects the analysis line with the smallest statistical error.
8.0 10.0 12.0 14.0 16.0
La of Hg is overlapped with Zn Kb.
So, its SE is greater than Lb of Hg.
Software chose Lb for analysis
NOTE: Software records why this line
was chosen, you can see that record.
XRF results are affected by sample matrix and
must be analyzed with the appropriate calibration/recipe.
Fe alloy Resin Cu alloy
Previous models required an operator to manually select
recipes for each measurement. This can result in mistakes
as an operator’s judgment of a material could vary.
Material ID Benefit
This is your only task nowThese were your tasks
Material ID eliminates operation steps and
potential operator error because the
software automatically selects the proper calibration.
Each software/PC has a database that can be shared
internally, across a network, and can perform
data search, view, analysis, reporting and printing.
