Product Overview
The Specac Golden Gate™ is globally recognized as the definitive high-performance diamond Attenuated Total Reflection (ATR) accessory. As the original monolithic diamond system, it has set the benchmark for analytical reliability for over two decades through its exceptionally robust construction. The heart of the accessory is a single-piece diamond crystal brazed into a tungsten carbide support, providing a chemically inert and mechanically indestructible sampling surface. This high-end engineering allows for the analysis of the toughest solids, abrasive powders, and highly reactive liquids that would typically damage or compromise standard ATR optics.
Designed to evolve with your laboratory’s needs, the Golden Gate features a modular architecture with interchangeable top-plates. This versatility enables researchers to transition seamlessly between routine ambient measurements and specialized applications, such as investigating supercritical fluids at 6,000 psi or performing low-temperature studies down to -150°C. The accessory's signature bridge design applies up to 80 lbs of force to ensure optimal sample-to-crystal contact, while the Benchmark™ baseplate system ensures permanent, high-precision optical alignment within virtually any FTIR spectrometer.
Key Features
- Monolithic Diamond Technology: Features a single-crystal diamond for maximum durability and chemical resistance, bonded into a rugged tungsten carbide mount.
- Extreme Sample Contact: The heavy-duty bridge assembly applies up to 80 lbs of force to achieve superior spectral quality from even the hardest solid materials.
- Modular Application Range: Supports interchangeable top-plates for high/low temperature, supercritical fluids, and reaction cell monitoring.
- Universal Compatibility: The Benchmark™ baseplate system provides easy installation and permanent alignment across all major spectrometer brands.
- Optimized Optical Throughput: Utilizes high-efficiency ZnSe or KRS-5 focusing lenses to deliver maximum energy to the detector.
