X-ray Powder Diffraction (XRD)

Description

The XRD Rigaku MiniFlex 600 XRD Diffractometer was powered and from the panel, the voltage and current were set at 30kV and 15 mA. The temperature was set at 21-23oC. The computer system was switched on and the software of XRD, TUMI was double clicked to run. The settings dialogue was clicked and all the required setting of power and temperature were checked to correspond to that of the XRD. The analyzed material was finely ground, homogenized, and average bulk composition is determined. The powdered sample was then prepared using the sample preparation block and compressed in the flat sample holder to create a flat, smooth surface that was later mounted on the sample stage in the xrd cabinet.

Sample was poured into the sample holder and then placed in the sample chamber column. Then the door was shut and confirmed from the computer. The sample was analysed using the reflection-transmission spinner stage using the Theta-Theta settings. Two-Theta starting position was 4 degrees and ends at 75 degrees with a two-theta step of 0.026261 at 8.67 seconds per step. Tube current was 40mA and the tension was 45VA. A Programmable Divergent Slit was used with a 5mm Width Mask and the Gonio Scan was used.

Packaging Instructions

For Liquid samples, per analysis, measure 5ml
Measure 2grams per analysis for solid samples
Liquid samples should be sent in sample bottles, pet bottles, or any air-tight container.
Solid samples should be sent in zip lock bags, sample bottles, or any air-tight container.
Samples should be labeled legibly with paper tape, marker, or writing pen.
Labels should be short and precise (not more than 3 words).
All samples must be strapped together and secured in a bag prior to transport.
Write the Following on the Bag, or Envelope “Allschoolabs Analysis – Receiver: Madison, 08163383206” then add the address of whichever collection center you are sending to.

Other Instructions

For XRD, if you can , please give us your compounds of interest so that we can match with such compounds
