Comparison between ICP and FAAS spectrometer
Icp is more expensive than AAS. Of course, it mainly depends on your purpose.

ICP can measure more than 70 elements.

The analysis speed is fast, and 5-8 elements can be measured in one minute.

Multi-element simultaneous analysis, customers can freely choose the number of elements and arrange the measurement order.

The detection limit is low, reaching the order of ppb, and Ba even reaches 0.7ppb.

The linear dynamic range is wide, up to 6 orders of magnitude, and the high and low content can be measured simultaneously.

The analysis cost is low, and a bottle of argon can be used for 8 hours.
