<h2 id="advantages">Advantages</h2>
<p>Compared to normal analyses methods, microanalysis:
</p>
<ul><li>Can resolve fine-scale variations in chemical elements.</li>
<li>Can be used to identify the presence and distribution of different phases in materials.</li>
<li>Requires less sample material and therefore can provide information on microscopic objects.</li></ul>
<h2 id="disadvantages">Disadvantages</h2>
<ul><li>Handling of small quantities is not always simple.</li>
<li>Higher accuracy of weighing is necessary (e.g. use of accurate <a href="/facts/Weighing_scale/6Yvv6frI">balance</a>).</li>
<li>Sample surface preparation can have a major impact on measurement results.</li></ul>
