Product Overview
The 700T Inductively Coupled Plasma Emission Spectrometer is a top-tier laboratory analyzer engineered for speed, sensitivity, and stability. Utilizing a high-sensitivity Photomultiplier Tube (PMT) as its detector, it can accurately test nearly 70 elements with exceptionally low detection limits.
Built around a self-developed solid-state RF generator and an advanced auto-tuning matching system, the 700T ensures maximum power efficiency and operational stability. Equipped with a dedicated circulating cooling water system and a highly sensitive sampling system (featuring an efficient nebulizer and a patented double-barrel spray chamber), the 700T is the definitive choice for high-throughput elemental analysis.
Core Analytical Advantages
1. Massive Elemental Coverage
Capable of testing over 70 elements, encompassing all metal elements and the vast majority of non-metal elements.
2. Rapid Multi-Element Simultaneous Testing
Single injection tests all target elements simultaneously, generating comprehensive results in one pass. Analysis speeds reach approximately 5 elements per minute, expandable up to 10 elements per minute.
3. Ultra-Low Detection Limits & Wide Linear Range
Achieves ppb-level detection limits for the vast majority of elements in solution. The wide linear range spans 5 to 6 orders of magnitude, allowing simultaneous testing of both high and low concentration samples.
4. Minimal Chemical Interference
Virtually eliminates chemical interference. Features real-time background subtraction for highly accurate and precise testing results.
5. Ultra-Low Operating Costs
In non-working states, the power, cooling water, and gas automatically shut off, eliminating standby costs. The system requires no long optical path warm-up (instant-on operation) and operates efficiently using only 99.99% purity Argon—saving at least one-third in gas costs compared to conventional systems.
Performance Highlights & Technical Features
Advanced Solid-State RF Generator
Features a self-developed all-solid-state RF power supply that is compact, highly efficient, and provides stable output power with comprehensive safety protections.
Fast & Accurate Auto-Matching
The load terminal utilizes self-developed fully automatic matching technology. This ensures rapid matching speed and high precision, guaranteeing maximum power delivery to the load and improving power supply efficiency.
Total Reflection Achromatic Optical System
Replaces convex lenses with concave reflectors for optical focusing. This innovative design eliminates chromatic aberration caused by differing elemental focal points and significantly boosts optical system efficiency. (Czerny-Turner type, 1000mm focal length).
High-Efficiency Sample Introduction
Equipped with a concentric high-efficiency nebulizer and a patented double-barrel extension spray chamber. Optional accessories include high-salt and HF-resistant nebulizers to meet specialized needs. All gas flows (Carrier, Plasma, Auxiliary) are precisely controlled by advanced Mass Flow Controllers (MFC).
Fully Automated Intelligent Operation
Highly automated—the instrument’s functions are entirely computer-controlled (except the main power switch). Software controls 3D flame adjustment (X, Y, Z axis), auto-ignition (one-click start), and observation height optimization. An optional autosampler enables fully unattended operation.
Smart Diagnostics & Database Management
Features powerful graphical diagnostics to monitor instrument status in real-time. Includes an open software database with thousands of spectral lines (user-extendable) to avoid interferences, real-time wavelength correction, and real-time matrix subtraction.
