Performing a Search/Match Operation

NOTE

A reference database is required to perform a Search/Match operation.

This tutorial was prepared using PDF 4+ 2009 as a reference database. You may have another

reference database.

If you have no database, you cannot perform this part of the tutorial concerning the Search/Match.

The following seven-step procedure describes the basic procedure for running EVA Search/Match,

using the default parameters.

The scan used is held as a tutorial file, BChips.RAW, found in the Tutorial directory.

These are boiling chips coming from the stockroom of the Department of Chemistry, North Dakota

State University.

The boiling chips are crushed Dolomite/calcite marble. Quartz from the precursor limestone is a third,

routinely identified phase. In the metamorphic rock, weak peaks from one or more layer Silicates are

detected. They may be too weak to identify by computer routines, but important low angle d-spacings,

familiar to clay mineralogists, suggest a Chlorite (e.g. Clinochlore) phase.

Steps

1. Creating a new EVA document and importing BChips.RAW.

2. Setting of the search parameters and performing the initial search.

3. Matching procedure:

Identification of Dolomite (pattern 00-036-0426), Calcite (01-89-1304) and Quartz (01-075-8322)

4. Preparing the residual scan.

5. Performing a subsequent search on the residual scan.

6. Matching procedure

Identification of Clinochlore (01-083-1365)

7. Saving the EVA document containing the scan.

Step 3: Matching Procedure

From the patterns listed in the dialog box, the user chooses the best candidates to identify the

unknown, by comparing the stick patterns with the peaks of the current scan.

Fig. 4: Candidate List with the first pattern selected

Check button

1. In the Candidate List tab, the first pattern in the list is selected: it is Dolomite. The

corresponding ghost stick pattern (sticks and dotted lines) is displayed in the

graphical view.

2. Compare the stick pattern with the current scan. The first pattern 00-036-0426

matches a part of the peaks of the scan.

3. Mark this pattern by selecting the corresponding check box (or by clicking the

Check button below the table). The pattern is associated to a color and the image

of its stick patterns remains when it is no longer selected (highlighted) in the

Candidate List.

4. Go down in the list using the arrow buttons below the table. Compare the stick

patterns to the scan peaks. The Calcite and Quartz patterns (01-089-1304 and 01-

075-8322) appear to match the scan. Select the corresponding check boxes: the

images of their stick patterns remain when they are no longer selected.

5. Leave the non-matching stick patterns unchecked.

and 01-075-8322

Results

The three main phases are found with the initial EVA Search/Match run. A residual scan must be

prepared to identify the last phase.

Step 4: Preparing the Residual Scan

The “explained areas” (peaks which were found by the search/match) given by the identified phases

must be removed.

1. In the Selected Candidates tab of the Search/Match (scan) dialog box, click Residue.

2. Click the first selected pattern in the Selection list: the areas to be removed are displayed as

ghosts in the graphical view. Adjust the width of the zone to exclude around the pattern sticks with

the slider if necessary.

3. Click the Apply button.

4. Proceed the same way for the other selected patterns. The removed zones are displayed using

the ghost color.

Step 5: Performing a Subsequent Search on the Residual Scan

1. In the graphical view, zoom in on the first half of the diagram (5° to about 36° 2θ). Working on

relatively low angles for the identification of clay materials is highly recommended.

1. Working only on relatively low angles for the identification of clay materials is

highly recommended. Thus, zoom in on the first half of the diagram (5° to about

2. In the Candidate List tab, the first pattern in the list is selected: it is Gadolinium

Zirconium Selenium (pattern PDF 04-003-8951). The corresponding ghost stick

pattern is displayed in the graphical view.

3. Compare the stick patterns to the current scan peaks. Identify the Clinochlore

(pattern PDF 01-083-1365) which ranks 5. It ranks 2 selecting the Mineral

database only.

4. Mark this pattern by selecting the corresponding check box (by clicking the Check

button below the table). The pattern is associated to a color. The image of its stick

patterns remains when it is no longer selected in the Candidate List.

5. Leave the non-matched stick patterns unchecked.

Tutorial

Performing an Automatic Search/Match Operation

NOTE

A reference database is required to perform a Search/Match operation.

This tutorial was prepared using PDF 4+ 2009 as a reference database. You may have another

reference database.

If you have no database, you cannot perform this part of the tutorial concerning the Search/Match.

The following 4-step procedure describes the basic procedure for running EVA Search/Match using

the automatic mode.

An Automatic Search is likely to deliver accurate results if the three following conditions are fulfilled:

low overlap between phases

every phase in the unknown shall have relative intensities matching the ones of its reference

pattern in the database

no phase showing a significant line broadening

On the contrary, the interactive Search/Match is quite insensitive to line overlaps, to relative intensity

mismatches, whereas line broadening is not a major issue, which makes the identification of phases

possible in complex scans, even with relatively strong preferred orientations.

One has to be very careful using the automatic search. It is great when the three conditions are

fulfilled, but this can hardly be guessed before trying. In praxis, one will often have to keep on

searching with the interactive Search/Match after a trial with the Automatic Search.

The scans used are held as tutorial files, m1.RAW, CPD-2.RAW and Mineral_Mixture.BRML found in

the Tutorial directory.

Steps

1. Creating a new EVA document and importing the scan

2. Setting of the search parameters and performing the initial search

3. Automatic matching procedure:

Identification of the compounds

Checking with a “normal” matching procedure (for the m1 scan)

4. Saving the EVA document containing the scan.

Results

The three phases found with the automatic EVA Search/Match run match well the scan and

corresponds to the expected results. Nevertheless it can be interesting to check with a “nonautomatic”

search/match.

From the patterns listed in the dialog box, the user chooses the best candidates to identify the

unknown, by comparing the stick patterns with the peaks of the current scan.

1. In the Candidate List tab, the first pattern in the list is selected: it is Calcite. The

corresponding ghost stick pattern (sticks and dotted lines) is displayed in the

2. Compare the stick pattern with the current scan. The first pattern 01-071-3699

matches a part of the peaks of the scan.

3. Mark this pattern by selecting the corresponding check box (or by clicking the

Check button below the table). The pattern is associated to a color and the image
