XT-9900N Intelligent Microwave Digestion/Extraction System
Product Introduction
The XT-9900N Intelligent Microwave Digestion/Extraction System is a high-performance laboratory sample preparation instrument designed for microwave digestion and extraction. It combines real non-burst variable-frequency microwave power control with dual-CPU monitoring to achieve accurate, automated regulation of temperature, pressure, and microwave input power.
With a maximum working temperature of 250°C, non-contact pressure control up to 5 MPa, and a pressure endurance of 6 MPa, the XT-9900N supports demanding sample preparation procedures while maintaining high operational safety.
Its programmable multi-step methods, intelligent pressure control, microwave “Shock” protection, abnormal-noise detection, and multiple pressure-relief mechanisms make it suitable for laboratories requiring reproducible and automated digestion or extraction workflows.

Performance Features
•  Variable-frequency microwave control: Real non-burst microwave power adjustment from 50–100% at 2450 MHz.
•  Dual-CPU monitoring: Independent interactive monitoring enables precise temperature and pressure control.
•  Automatic power adjustment: Microwave input power is automatically adjusted according to programmed conditions.
•  High-temperature and high-pressure operation: Supports up to 250°C and 5 MPa controlled pressure.
•  Programmable methods: Stores up to 9 programs, with 9 programmable steps per method.
•  Microwave “Shock” protection: Automatically interrupts microwave input when the pressure rise rate reaches ≥0.2 MPa/s and resumes operation after pressure decreases.
•  Automatic pressure calibration: Zero and full-range adjustment can be performed automatically.
•  Intelligent fault diagnosis: Detects abnormal conditions and displays diagnostic information in real time.
•  Remote operation: Supports remote control for convenient and safer operation.
•  Multiple safety protections: Includes overpressure, overheating, abnormal-noise, emergency-stop, pressure-relief, and protective-cover mechanisms.
•  Easy operation: Menu-based interface and automatic system self-check simplify method setup and routine operation.

Working Principle
The XT-9900N uses 2450 MHz microwave energy to heat samples rapidly and uniformly inside a sealed digestion vessel. Microwave power is continuously regulated according to programmed temperature and pressure conditions.
A dual-CPU control system continuously monitors operating parameters and automatically adjusts microwave input power. Temperature can be controlled up to 250°C, while non-contact pressure measurement and automatic pressure control maintain the programmed reaction conditions.
During operation, the system monitors the pressure rise rate. If pressure increases too rapidly, the microwave source is automatically interrupted by the microwave “Shock” protection function. Once pressure returns to a safe level, microwave input can automatically resume.
The combination of microwave heating, programmable multi-stage control, automatic pressure regulation, and integrated safety protection enables efficient and reproducible sample digestion and extraction.

Safety Protection System
The XT-9900N incorporates multiple safety mechanisms for high-pressure microwave sample preparation:
1. High-pressure external vessel: PSF vessel with PPS liner, rated to 6 MPa.
2. Overheating protection: Automatically warns and suspends microwave radiation when overheating is detected.
3. Abnormal-noise detection: Detects unusual chamber noise and automatically stops microwave generation.
4. Overpressure protection: Automatic pressure matching, pressure-rise limitation, and warning.
5. Emergency suspension: Operation can be stopped using the emergency button or remote control.
6. Dual pressure relief: Air-bleed hole and bursting-film mechanisms provide additional pressure relief.
7. High-strength protective cover: PC protective cover helps shield operators during operation.

Applications
