CheXray Instrumentation

 

MicroSTAR-H APEX II (ChexSTAR: RUA # 1091)

X-ray Source: Microfocus Rotating Anode (Cu-Kα radiation)

Goniostat: Kappa Geometry with DX (Enraf-Nonius build)

Detector: APEX II

Low Temperature Device: Oxford Cryostream 700 (90-400 K; 0.1 K resolution)

 

Sample Recommendations:

Light organic (no heavy atoms) and inorganic/organometallic crystals (1st row transition/main group metals ok (Cr → Co better on Mo-Kα), 2nd row not recommended, 3rd row, lanthanides or actinides prohibited).

Ideal for absolute stereochemistry determinations. Face indexing available.

Crystal size: 10-100 microns.

 

APEX II QUAZAR (ChexQUAZAR: RUA # 1062)
