Performance Work Statement (PWS)

Questron QWave 1000-Watt Microwave Digestion System

1.0 Background

The Product Test Center requires a high-power, high-performance microwave digestion system to prepare chemically resistant and complex sample matrices, including but not limited to, titanium alloys, cobalt, tungsten ores, and various steels for elemental analysis.

This system will supplement the laboratory's existing Questron Vulcan S Uno digestor, providing a necessary capability for samples that require the high pressures and temperatures unique to microwave technology. This acquisition seeks to standardize the laboratory's digestion platforms to ensure operational interoperability.

2.0 Scope

The contractor shall provide a complete, "turnkey" Questron QWave 1000 Watt Microwave Digestion System. This includes the core instrument, all necessary high-pressure vessels and accessories, software, delivery, on-site installation by a certified technician, system verification, comprehensive operator training, and a full warranty.

3.0 Performance Requirements

The system shall meet the following minimum performance requirements:

• 3.1 Digestion Performance: The system must be capable of achieving complete and reproducible digestion of difficult-to-digest materials, specifically including Titanium 6-4, tungsten ores, and specialty steels. The resulting solution must be clear, free of particulates, and suitable for trace metals analysis.

• 3.2 Throughput: The system shall be capable of digesting a minimum of 12 samples simultaneously using the specified high-pressure vessels.

• 3.3 Safety: The system must provide maximum operator safety through multiple layers of monitoring and control, including real-time temperature and pressure control for all vessels, automatic microwave power adjustment to prevent over-pressurization, and a robust, blast-resistant cavity door.

• 3.4 Interoperability: The system must be fully compatible with the laboratory’s existing Questron equipment ecosystem. This requires a common software control platform and the ability to use interchangeable sample racks and vials post-digestion to streamline the workflow with the existing Questron Vulcan S Uno (s/n

VN24-1005).

4.0 Deliverables

The contractor shall provide the following:
