This should be the theme <strong>of</strong> the shell for industrial chemists, as it accurately portrays the<br />

daily lives <strong>of</strong> every laboratory in the industry.<br />

As thought in academy we always known how to start, deploy, and complete an analysis<br />

(nothing like using the logical sequence <strong>of</strong> a survey for cations and anions as learned in<br />

qualitative analytical chemistry). With the resources <strong>of</strong> equipment now available at the<br />

university - or at least should be - we also develop a good knowledge <strong>of</strong> instrumental<br />

analysis and, aided by access to computers in existence today, <strong>of</strong> chemometrics. Nothing<br />

like what we had 40 years ago.<br />

Over time we have obtained excellent analytical results more accurate and faster with the<br />

use <strong>of</strong> the latest equipment. However, if it was to be perform, the same analysis, using<br />

conventional methods and techniques (such as gravimetric/ titration analysis), we would<br />

find ourselves in trouble. Skills were lost and worse, knowledge. However things can be<br />

even worse, now there is an aggravating circumstance: that the outcome <strong>of</strong> the machine<br />

is regarded as divine truth.<br />

For new equipment manufacturers they “teach” what buttons to push to get the results,<br />

but for the correct interpretation <strong>of</strong> them, we still relay on academic support. The university<br />

must provide the knowledge bases, and show how and where to seek information that<br />

may be necessary <strong>of</strong> pr<strong>of</strong>essional development <strong>of</strong> their students.<br />

Some very good journals, for example, <strong>Analytical</strong> <strong>Chemistry</strong>, brings excellent articles, but<br />

<strong>of</strong> little use in practice <strong>of</strong> the laboratory industry. Try just look for one that instructs how<br />

to open a sample.<br />

The university has a major role, instill the habit <strong>of</strong> think.<br />
