Bidirectional observation with vertical torch
Applicable to areas with high sensitivity requirements, and providing a relatively wide range of versatility.
Suitable for applications with complex matrices, such as metals, oil products, geological and mineral samples, and etc.
EXPEC Technology adheres to the responsibility and mission of the “Future Laboratory Explorer”. The company has created the new generation EXPEC6500 ICP-OES after years of technology accumulation and devotion in research and development, and made a new leap in core technologies such as RF power supplies, large area array detectors, and methods for observation with plasma torch flame. The ICP-OES supports the analysis of rare earths with requirements for full-spectrum high-resolution, and the analysis of Cl/Br elements over the deep ultraviolet waveband. At the same time, a variety of easy-to-use functions and intelligent auxiliary equipment have been developed to form an intelligent analysis system, which can help operators improve the efficiency, free them from complicated and repetitive tasks, and create value more effectively.
The EXPEC 6500 inductively coupled plasma emission spectrometer adopts a with newly developed vertical torch dual observation technology, which can measure elements of relatively large differences in content in a complex matrix. The patented self-excited all-solid-state RF power supply ensures that the system will have excellent adaptability to samples, and offers a low-power standby mode, which greatly reduces argon consumption. The unique large-area array high-sensitivity ECCD sensor brings better performance to the product. Combined with many years of experience of EXPEC series in spectroscopy instrument development, the EXPEC 6500 Type ICP-OES product offers the 8-hour stability index RSD of < 1%, and the precision RSD of twin internal standard method of < 0.1%, and thus brings you stable and reliable analysis results.
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.
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 500-1600W, 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.
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 time, and finish analyzing 72 elements in 10s.
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
Fully digital power supply control: the RF power supply based on dual power supply technology is continuously adjustable over the wide power range of 500W to 1600W, with better sample adaptability.
Square inch large area array CCD detector
The pixel size is large, which brings about high-sensitivity response, and the overall area is large, with which a wider spectral range can
be obtained while the high resolution is maintained.

Back-vented anti-overflow design
Even in the 800 nm to 900 nm waveband where the argon line overflow is strong, the spectrum of effective elements can still be clearly distinguished.
Good UV response
The intensity of C and Al spectral lines
around 160 nm is good.
The ultraviolet waveband hierarchy is
clearly visible.
Intelligent attenuation, with which samples of concentration of 1 to 100 times can be handled easily
The attenuation multiple is automatically increased according to the high and low concentration of elements to complete the analysis of a sample with a steep gradient of the elements of high and low concentrations at one time without repeated dilution, which reduces the difficulty of sample pretreatment
Patented intelligent integration design: Signals and background are acquired at synchronously; the exposure time depends on the light intensity of the spectrum; the best exposure time of the spectrum is calculated automatically; the light intensity is normalization calculated; the working curve is combination calculated; the integration time control is accurate to the microsecond; the dynamic range is widened; and the repeated dilution of the sample is avoided.
Effective dilution of high salt samples of more than 10% is achieved by adding a channel of argon gas for dilution which is controlled by MFC before the aerosol in the atomization chamber enters the torch, and the difficulty of sample pretreatment is thus reduced.
Only C, N, and Ar spectral lines are used for start-up and ignition, and the spectrum correction is automatically completed without specific sample injection.
The patented full-spectrum real-time correction (FSC) technology uses the characteristic line of the non-interfering neon to correct the subtle deviations of the spectrum in real time.
so that better spectral integration can be achieved to ensure good long-term stability.
Multi-channel digital mass flow controller, providing precise control over each channel of argon, with the control accuracy at 0.01 L/min, to ensure the stability of the data measured.
The high-precision 12-rotor 4-channel peristaltic pump ensures stable sample injection, and can add internal standard solution and standard addition solution according to the needs, which is conducive to complex sample analysis.
Fully split-body torch, the installation of which is self-collimating; for different applications, only the center tube needs to be replaced, which greatly reduces costs.
