Magnets And Cryostats
The CRYS-582/CRYL-583 are the liquid nitrogen cryostat. The CRYS-582 is the cryostat for solid samples with a temperature range from ambient down to -180 °C and accepts solid samples with up to 10 mm diameter. The CRYL-583 is the cryostat for liquid samples with a temperature range from ambient down to -150 °C and accepts rectangular cells of up to 5 mm pathlength. For controlling the sample temperature in the cryostat, the TC-22HK2 Temperature Controller is required and for insulating sample holder unit and liquid nitrogen vessel from ambient, the vacuum pump (G-50D etc.) is required. The CRYS-582/CRYL-583 can be mounted on the sample compartment of the J-1500 and the MCD-581 eletrco-magnet.
MCD is effective for research on electronic states of molecules and atoms obtained through optical activity induced by a magnetic field. Permanent magnet, electromagnets and superconducting magnets are available.
MCD signal intensity is proportional to the magnetic field strength applied, so different types of magnets can be used:
- Permanent magnets with field up to 1.6 tesla at ambient temperature
- Electromagnets with field up to 1.5 tesla and low temperature cryostats
- PM-491 Permanent magnet 1.6 tesla
- MCD-581Electromagnet 1.5 tesla, water cooled
