The Integra XMP simultaneous/sequential ICP provides fast and powerful solutions for laboratories with high-volume routine analytical requirements.
The instrument incorporates total computer control of all instrument functions, and can be run unattended to fully exploit their high sample throughput capabilities.
The thermostatted 1.0 m Paschen-Runge vacuum polychromator can be fitted with up to 60 channels, according to individual user requirements. The XMP, with the addition of a high-resolution 0.75 m Czerny-Turner monochromator, ofters the extra flexibility to analyse at any wavelength from 160 to 800 nm.
The XMP includes the following outstanding features:
- Mass Flow Gas Control. Precise control of each of the torch's three argon gas flows using mass flow technology guarantees the ultimate in plasma stability and measurement precision.
- Unparalleled Optical Stability. Integra's thermostatted polychromator system achieves outstanding optical stability to give you confidence in your analytical results.
- Unique 2-or 3-Axis Viewing Adjustment. Computer controlled adjustment of the plasma viewing position ensures precise alignment of each optical channel and optimization of viewing height for maximum performance.
- Total Computer Control. With all instrument parameters under computer control, including plasma ignition, power, gas flows and viewing height, Integra XP/XMP can be rapidly optimized for any analysis.
- Unique Demountable Torch. Integra's efticient torch design provides outstanding performance at low gas flows and low power.
- Efficient RF Generator. Integra's 40.68 MHz RF generator, combined with the high efficiency torch, provides the highest energy transfer from the plasma to your sample, oftering superb performance and stability for all matrices.
- Comprehensive Service Diagnostics. Integra's extensive use of diagnostic meters and built-in service software ensure rapid fault-finding.
- Outstanding Vacuum Performance. Vacuum operation is provided as standard, allowing analysis in the VUV region, including the most sensitive AI, P, S, N, and B wavelengths.
