Seven Advantages of a High-Speed Handheld XRF Analyzer

The high-speed performance of the handheld ProSpector 3 XRF analyzer is a crucial quality indicator. First and foremost, speed determines work productivity - the number of analyses per unit of time, and consequently, the cost per measurement. Higher speed equates to greater economic efficiency from using the tool. At full capacity, the ProSpector 3 can perform the same volume of work in a shift as three competing XRF analyzers, effectively costing businesses three times less.

The second key factor is operator convenience. During analysis, the operator must hold the spectrometer still in direct contact with the sample. Naturally, it's much easier to maintain this position for 2-3 seconds than for 15-20 seconds.

Thirdly, there's the safety aspect of using the analyzer. Although in all modern analyzers the dose of scattered X-ray radiation does not exceed permissible levels, it is never zero. Therefore, the shorter the operating time of the X-ray tube in 'hard' mode (with high anode voltage), the less stray radiation is emitted into the surrounding environment. Thanks to its record speed, the ProSpector 3 only activates this mode for no more than one second!

The fourth factor is the longevity of the X-ray tube. The less time the tube operates, the longer its lifespan. Thus, the risk of needing to replace a malfunctioning X-ray tube in the ProSpector 3 is minimized.

Fifth is the battery life of the analyzer. Since the activated X-ray tube consumes power up to 8 Watts (about 80% of the total consumption of the analyzer), turning it on for such a short time significantly reduces overall power consumption, thereby proportionally increasing battery life.

Besides reducing ownership costs and improving comfort and safety in operation, the high-speed performance of the X-ray spectrometer also enhances its analytical characteristics. All else being equal, the statistical error of measurement results is inversely proportional to the square root of the number of X-ray photons registered in the spectrum. Hence, the sixth advantage of a high-speed analyzer is the precision of analysis. The ProSpector 3 with a speed of 500,000 cps is twice as accurate as other handheld XRFs.

Similarly, the statistics of X-ray photons in the spectrum affect the detection limits of elements – the minimum concentrations that the device can detect in a sample. The seventh advantage is the doubly lower detection limits – a crucial factor for analytical tasks involving the measurement of low and trace element concentrations (RoHS, environmental monitoring, etc.).
