EXPEC-6500 Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES)

A new generation of vertical torch dual observation technology.

The EXPEC-6500 product adopts a newly developed vertical torch dual observation technology, which greatly reduces argon consumption and torch consumption, and can be used to measure elements of relatively large differences in content in a complex matrix. The vertical torch prevents high salt deposition, and the radial observation avoids matrix interference, with which better sensitivity and repeatability can be achieved. The innovative vertical observation technology with adjustable height can optimize the observation position for different elements.

Patented self-excited all-solid-state RF power supply.

The product integrates the self-excited all-solid-state RF power supply with EXPEC’s third-generation patented technology to ensure that the equipment has better sample adaptability and stability. There won’t be any flameout even if organic samples or even air is directly injected, thus eliminating the need for pre-treatment and preparation processes for organic samples such as oil products. The power range of the power supply is (500-1600) W, and its power adjustment range is better than that of most mainstream products. In the 500W low-power standby mode, the argon consumption is 5L/min, which adequately saves the cost of argon consumables for the user, and eliminates the waiting time required between the repeated turning on and off of the stable RF power supply.

The large area array ECCD sensor improves the sensitivity and spectral range of the instrument.

As for the proprietary large area array ECCD sensor, its excellent low noise and deep ultraviolet response combined with anti-overflow design, provide the EXPEC 6500 with good detection limits. The large area array design ensures that the instrument can truly acquire the full spectrum in one take, and finish analyzing 72 elements in 10s.

8-hour stability RSD < 1%.

Through high-precision temperature gradient field simulation, and air duct fluid dynamics simulation, in combination with repeated practical verification, the internal structure design has been optimized, which gives the structure greater resistance to environmental temperatures. Since the stability design of many key components such as RF power supply and injection system is incorporated into the instrument, the high stability of 8 hours RSD is below 1%, which has reached the leading level internationally.
