I’m doing synthesis optimization.
I controlled synthesis method, however I did like below.
e.g. Synthesis run 1-10 : XRD machine 1
Synthesis run 11-20 : XRD machine 2
so for e.g. 111 peak intensity signal is different, e.g. (111) machine 1 = ~100,000
(111) machine 2 = 5,000
How can I compare 1-20 runs sample ?
if I did same machine, it will be no problem, but at the moment, machine 1 was under maintenance.
sample are powder type. peak point are a bit shifted however intensity are important to optimize synthesis method.
how can I comapare if I use different XRD machine.
Dear Dr. Seongho Jeon
In XRD, peak intensity refers to the area under the peak, not the peak height. please let me know what (111) machine1 =100,000 and (111) machine2 = 5,000 are for peak area value or peak height counts
Now, if the two equipment used different wave length in the spectrum of the x-ray beam of your XRD equipment , i.e., K-alpha or K-beta lines , then expect about 10% variation in the results obtained from equipment 1 and 2 as the wave lengths of Cu K-alpha is 1.54 Å and for Cu K-beta is 1.39 Å.
Your feedback is welcome .... My best regards .
Seongho Jeon The peak intensity differs due to different X-ray beams utilized. While comparing samples, you need the 2theta (diffraction angle) values. You can normalize the data (in Origin or Excel) from both the machines, and plot them together, so that the intensity levels don't hinder the comparison.
