QL-ICPMS-7000 Inductively Coupled Plasma Mass Spectrometer
The QL-ICPMS-7000 is a high-performance inductively coupled plasma mass spectrometer designed for trace and ultra-trace elemental analysis. With ≤3 ppt detection limits, a dynamic range exceeding 9 orders of magnitude, and advanced interference reduction, it delivers reliable analytical precision for environmental, food, industrial, and research laboratories.
OVERVIEW
Description
The QL-ICPMS-7000 Inductively Coupled Plasma Mass Spectrometer is an advanced analytical platform. It is engineered for high-sensitivity elemental analysis across a broad range of applications. The instrument is designed with a balanced drive ion source, low-background dual off-axis ion optics, and a six-pole collision/reaction cell. As a result, the system delivers exceptional signal stability, low interference, and long-term operational reliability.
The instrument achieves ultra-trace detection limits of ≤3 ppt while maintaining a linear dynamic range greater than 9 orders of magnitude. This enables accurate quantification from trace to high-concentration samples. In addition, a pure molybdenum quadrupole mass analyzer with low-frequency drive ensures excellent mass stability. It also provides extended mass range coverage from lithium to uranium.
The QL-ICPMS-7000 supports full automation and system integration, including autosamplers, microwave digestion systems, and HPLC-ICP-MS configurations. Real-time plasma visualization, automatic tuning, and comprehensive quality control software further enhance usability and regulatory compliance.
Built for demanding analytical environments, the QL-ICPMS-7000 provides laboratories with robust performance, reduced maintenance requirements, and consistent, high-quality data.
