Diacell® µScopeDAC-HT(G)
Raman and FTIR µSpectroscopy, Pmax = 50 GPa, Tmax = 900 K, WD = 12 mm, A = 52°
Diacell μScopeDAC Series
- The Diacell® μScopeDAC-HT(G) is compatible with commercially available spectroscopic microscopes
- Maximum pressures of up to above 50 GPa are obtained with the Diacell® μScopeDAC-HT(G)
- Fitted with type IIas ultra-low fluorescence & ultra-low birefringence diamond anvils the cell is ideal for Infrared and Raman microscopic sample analysis
- The DAC is equipped with an internal compact gasket heater that enables research up to 900 K.
- Being gas membrane driven means that the pressure within the cell can be changed whilst the sample is mounted in the microscope stage
Description
The Diacell® μScopeDAC-HT(G), gas membrane driven, high-temperature, diamond anvil cell, meets the growing need to reach very high pressures and be compatible with the optical and physical constraints of microscopes. It is suitable for optical work under FTIR and Raman microscopes and has an internal gasket heater that operates to 900 K. The cell is supplied fitted with a K-type thermocouple and is suitable for water cooling.
The Diacell® μScopeDAC-HT(G) is only 25 mm thick along the optical axis, and is symmetrical about the sample. Thus, the physical distance from the objective to the sample between the diamond anvils is just 12 mm. This makes the Diacell® μScopeDAC-HT(G) compatible with most, if not all, commercial Raman and FTIR systems.
Applications
A large and increasing percentage of optical and spectroscopic observations is now made using microscopes. In particular, Raman instruments are commonly sold with integral microscopes to enable efficient scattered light collection, as well as to permit Raman mapping of complex samples. Similarly, FTIR spectrometers are often supplied with reflecting (Cassegrain) microscopes. The Diacell® μScopeDAC-HT(G) is particularly suited for such applications.

FAQs
What is the maximum pressure I can achieve with the µScopeDAC-HT(G) and a given culet size?
| Culet size (µm) | 200 | 300 | 400 | 500 | 600 | 800 | 1000 |
| Pmax (GPa) (*) | N/A | 74 | 48 | 31 | 21 | 12 | 8 |
(*) The Pmax values are only indicative. The maximum pressure achievable with a DAC is influenced by many others experimental parameters, like the gasket characteristics (material, thickness and hole size) or the pressure transmitting medium.
