Dear friends,
my results, participation number P020.

Using the 
- Oxford Crysosystems CSM program, 
==> only raw data (no peak search)

I found the results with the help of ICDD set 51.

Many thanks for the idea of such a Search/Match Round Robin.

Best regards.


Dear organizers,
I'm sorry, but again in the last minute. There is too much of daily business.
Every determination was done in about 10 minutes ...

But again many thanks for the idea.
Yesterday I converted the data to my usual STOE- raw data format to see 
nom my results in 'my' graphic, see Figures.

Studying the element information I am glad that some presented phases 
of the first step are ok.

I assume, that the measurements were taken with a zero shift. Normally 
I do not use this in my search/match. The diffractometer is checked for 
angle (and intensity) before the first measurement after every new switch
on using a standard sample.

Sorry I have no experience in organic chemistry, therefore I prefer to 
be reserved.

Here the actual phase analysis, the now added / changed phases are red 
marked :

			PDF-number
Sample 1:

Apatite			15-876			ok
Quartz			46-1045 		It seems that there exists a 
systematic angle error of the
measured data to higher angles.
Gormanite		36-403			confirmed, ok, peak shift
Dolomite structure	e.g. 79-1346		D Giko
Zn(N3)2 (NH3)2	71-2225	possible		not present



Sample 2:

Searching as single phase I found :

C14 H24 F2 N2 O40 Si20	48-475		reflection arrangement is ok, but lattice 
parameters may differ
C8 H20 N F6 U		26-1993	two relatively strong lines are absent

I have no new ideas and would discuss this with the customer …., after having 
a look to the 'anorganic elements'. 


Sample 3:

Obviuously my first ideas were not the best …..
NaHCO3		72-1663 or 73-1390
Hydroxylapatite	9-432

Searching now with 'C,H,N,O must be included, and only this' 
I find

C13 H10 N2 O		19-1946		measurement with peak shift to higher 
angles (?)

The proposed phase C13 H10 N2 O4 with PDF 2-201 is not present.

C15 H13 N3 O4		51-2367		?




Sample 4 :

PbO			35-1482		here better : PbO Litharge 5-561
Pb5 O4 SO4		23-333
(PbO)3 (Pb(SO4)) H2O	88-551

I think, that this is ok.
