Exact control of plasma conditions

SPECTROLAB’s high-energy plasma generator — among the most robust available — produces an extremely stable discharge to excite the sample in the unit’s argon atmosphere. It’s digitally guided for exact control of plasma conditions with extreme resolution, high fidelity, and accelerated results. To avoid any high-voltage interferences, the generator and ignition board are placed close to the spark stand. The system furnishes all relevant parameter settings to create ideal plasma conditions for optimum analytical performance.

New spark stand

The spark stand has been redesigned for this latest SPECTROLAB generation. This new design helps reduce residue along with the system’s argon cleaning flush. The system monitors number of measurements and use of material so it can provide convenient software reminders when stand maintenance may be required. And on SPECTROLAB hybrid models, an optional and additional CCD optic can be connected to the stand.

The new industry standards

SPECTROLAB: Hybrid. SPECTRO established new benchmarks with the introduction of the first true hybrid SPECTROLAB system in 2007. Today, the third-generation hybrid model provides unbeatable precision, flexibility, and stability for specialized research and development (R&D) laboratories. This hybrid SPECTROLAB is particularly suitable for testing new materials, and for analyzing precious metals trace elements and inclusions.

SPECTROLAB: All-CCD. Besides its unbeatable flexibility, the new all-CCD model SPECTROLAB musters impressive reproducibility, stability, and speed. It also boasts technological advantages such as iCAL, online drift correction, plasma observation, dynamic preburn, and direct plasma view over the entire wavelength range. So it’s ideal for time-critical applications including process control and quality control inspection of incoming and outgoing materials. It also delivers top performance on specialized applications such as analysis of carbon in nodular cast iron.

Optimized components positioning

Separate compartment

Power supplies, the new high-speed readout system, and other electronic components are isolated in a separate compartment atop the chassis. This ensures optimum ambient temperature for their operation, and prevents them from affecting optical systems. It also ensures easy access if service is needed.

Air Conditioning

Improved air cooling

A redesigned, dedicated air-cooling system uses robust, reliable standard techniques. It’s positioned atop a new insulation shell for the optical system. Cool air flows downward, passing fully over the outside surface of the optical system and maintaining it at a stable temperature of 20° C (68° F). This air is circulated by a single fan, and vented to the outside. Result: optimum conditions for ideal optical performance.

Optical System

High-efficiency light distribution

The light created within the plasma under SPECTROLAB’s argon atmosphere is measured simultaneously in both segments of the optic system. The analyzer’s innovative Optimized Rowland Circle Alignment (ORCA) technology utilizes few mirrors, providing direct, high-luminance paths that minimize light loss. So the light intensity level of each separated spectral ray can be precisely measured and directly correlated with the concentration levels of metals present in the sample.
