QWave Microwave Assisted Digestion System — Questron Technologies closed vessel sample preparation

Platform

Two Models, One Answer

The QWave 2000 and QWave 1000 are two distinct configurations addressing different throughput and application requirements. Both share the same safety architecture and vessel sets.

⚙

QWave 2000 — Dual-Magnetron High Power

Two 900 W magnetrons, 1800 W total. Closed vessel only. 1-watt increment precision power control. Power: 1800 W · eVHP capacity: 18 vessels · LVHT capacity: 36 vessels.

⚙

QWave 1000 — Closed & Open Vessel

Single-magnetron design. Supports both closed and open vessel protocols. External exhaust fan standard for open vessel. Power: 900 W · eVHP capacity: 12 vessels · LVHT capacity: 24 vessels.

QWave eVHP and LVHT vessel sets — OPGuard individual pressure monitoring

Safety Technology

OPGuard: Individual Overpressure Protection

Per-vessel independent pressure monitoring with a reclosable venting mechanism. Cross-contamination risk is kept to a minimum; operator safety is maintained without compromise.

🔒

Controlled Vertical Venting

When the pressure control limit is reached, the system vents vertically in a controlled manner. Cross-contamination to adjacent vessels is minimised; sample integrity is preserved.

🔔

Two-Level Protection

After a minor vent event, the digestion method can continue from where it left off. A major vent event cuts magnetron power automatically and triggers an audible alarm with on-screen visual warnings.

🌡

Per-Vessel Independent Monitoring

Temperature and pressure are measured independently in every vessel. Abnormal heating is detected automatically; the safety system responds without requiring operator intervention.

Frequently Asked Questions

What You Wonder About

The QWave 2000 is a dual-magnetron system delivering 1800 W total output via two 900 W magnetrons; it is designed exclusively for closed vessel digestion. The QWave 1000 is a single-magnetron unit that supports both closed and open vessel protocols. An external exhaust fan for safe removal of acid vapours is standard in the open vessel configuration.

eVHP handles demanding matrices at pressures up to 151 bar and offers 18 vessels per run on the QWave 2000 (12 on the QWave 1000). LVHT is optimised for high-throughput routine analysis with 36 vessels per run; moderate temperature and pressure conditions are sufficient for most environmental and food matrices.

OPGuard is a reclosable individual overpressure protection system that monitors every vessel independently. When the pressure control limit is exceeded, pressure is vented vertically in a controlled direction to prevent cross-contamination between vessels. A major venting event cuts magnetron power automatically and triggers an audible alarm with on-screen visual warnings.

QWave comes with a pre-loaded method library covering EPA and other internationally recognised standard methods. Users can create, store, and manage more than 1000 custom multi-step methods via the touchscreen interface.

QBlock is an optional block digestion unit that integrates with QWave. It is used for low-temperature pre-digestion of organically rich samples prior to microwave processing, boric acid treatment of HF-containing digests, and post-digestion acid evaporation. All steps are performed within the original digestion vessel liner, eliminating cross-contamination from multiple vial transfers.

The system automatically logs all digestion parameters — temperature, power, pressure, and OPGuard events — throughout every run. With 10 GB of onboard storage and built-in data export and print functionality, every batch is fully traceable and auditable.
