aard

-De indruk van

het

geheel

was: meer consoliderend dan innoverend. Er

'"as minder over niem"e dure instrumentele technieken

en

meer

over

praktische toepassingen

van

reeds

l

ane

bestaande technieken. Ook

be-zinning

over economisch werken.

Er

\<las

een

speciale middag ge\olijd

aan

Analytische

chemie en

maatschap-pij, \olaarbij milieuproblematiek

en

voedingsmiddelenonderzoek

aan

de

orde k\<lamen.

Pfannhauser stelde hierbij dat de

analytische

chemie in

een

dilemma

geraakt

is tussen \•letgeving,

economie en

consument. Elk van deze

vraagt

analytische

controle:

(

Anal!tische

Consument

Hij

en

Ottendorfer wezen

op

de veel

grotere complexiteit zowel

van de

vragen

als

van de

analytische

technieken t.a.v.

vroeger

:

bioaccumule-rende verbindingen vs. vochtgehalte;

electrochemie,

GC-MS in

<

ppb vs.

pH meter.

Fresenius

hanteerde

het valeende

schema

van

aandachtsgebieden

voor

onderzoek

van ongewenste

stoffen:

-

Hansterneming

-

Heting

b.v.

f

luorimetrie

-

Bevestiging

vergelijken

b.v.: HPLC: meer reproduceerbaar

-

Hetgeving

In de discussie van deze

speciale sessie

kwam o.a. het

probleem aan

de

orde

dat

er

niet genoeg

vertrouwen is in de

analytisc

he

methode.

Vol-gens

Egan is dit

inderdaad een groot

probleem.

-- 3

-Fresenius pleitte voor meerdere onafhankelijke methoden, maar ook bij

een

officiële methode zullen de resultaten niet kloppen

als

intussen

het monster verandert

.

Steeds is het de verant1·10ordelijkheid van de

analyticus om

te

bepalen of het

resultaat

juist is of niet. Verder

werd er

gevraagd

ook mislukkingen te publiceren. Malissa merkte op dat

1~ij

duidelijke definities nodig hebben (en daar

schort

het, blijkens

het voorafgaande IUPAC symposium over harmonisatie van

ringonderzoe-ken, nog

1~el

aan),

en dat het

eis

is bij te blijven,

1~aarbij

hij

spe-ciaal noemde bijscholingscursussen van post-gegradereerden.

In een algemene lezing stelde The Gaveroment Chemist,

Egan,

dat

een

methode die ondersteund 1wrd

t

door

ringonderzoek, sterk staat.

Hij

onderscheidde verschillende "soorten": analytisch

chemici:

-

Chemisch analyticus

- Gespecialiseerd analyticus

-

Instrumentele technoloog

- Produktie analyticus

-

Instructeurs

Tentoonstel-lingen

In

een

lezing

over

referentiematerialen definieerde Alvarez

"defini-tieve

methoden

"

,

dat zijn

methoden zonder

systematische

fout

en

~~aar­

van

de

onnauwkeurigheid

bekend is.

Ramendik beschreef

spark souree

massaspectrometrie (SSMS) als

een van

de

meest

universele

en

informatieve methoden voor

elementanalyse

.

70

elementen in

10-2 - 10-3

ppm

gebied.

Nog

1~einig

toegepast

omdat de

instrumenten duur

en

inge

wikkeld zijn

en ook

de

complexe analytische

procedure nog meer tot de kunst dan

tot

de wetenschap behoort. De

com-merciele

apparaturen

werken nog teveel onder

ongecontroleerde

omstan-digheden

.

De

eerste

resultaten met

een

nieuwe

eigenbouw generator zijn

hoopgevend. Net

een

nieuwe

generatie

kleine NS

en

kan SS-NS voor

inor-ganische

muitielement analyse

een

referentiemethode

worden om andere

methoden te testen.

Tentoonstelling

Tijdens het congres 1vas er een tentoonstelling van instrumenten, che-micaliën, boeken en tijdschriften, \vaar o.a. Labsystems, Perkin Elmer, ARL, Philips, Nerck en de grote uitgeverijen als Elsevier en Springer vertegem10ordigd waren. Opvallend \vas het ontbreken van LKB en diens Finse dochter ,.;rallac Oy.

Perkin Elmer komt met een Zeeman effect oven voor hun model 5000. Vol-gens deskundigen zou dit apparaat in het optimale gebied \verken (in tegenstelling tot het apparaat van Hi tachi).
