FIT screening

Dikkedarmkanker, ook wel colorectaal carcinoom, is een veelvoorkomende ziekte onder voornamelijk ouderen. Het detecteren van dikke darmkanker in een vroeg stadium kan de overlevingskans van een patiënt aanzienlijk vergroten. Door gebruik te maken van een fecale immunochemische test (FIT) worden kleine hoeveelheden bloed (met behulp van antilichamen voor humaan hemoglobine) opgespoord in ontlastingsmonsters.


Sysmex biedt FIT-tests aan voor twee hoofdgroepen: grootschalig tests voor nationale of regionale bevolkingsonderzoeken, en symptomatische tests die hoofdzakelijk plaatsvinden in ziekenhuizen of klinische omgevingen. Lees hier meer over op onze FIT screening microsite http://www.fitscreening.eu/

Tensiometers & Contact Angle Meters

Liquids (Surface and Interfacial Tension)

Predicting the performance of surfactants does not only demand knowledge of its structure and material composition but also knowledge of fundamental properties like surface and interfacial tension. Study of processes at interfaces are important to explain wetting, foam formation and emulsification. We have to distinguish between static and dynamic surface tension measurements. For time dependant processes where new interfaces are generated within fractions of a second, the understanding of the surfactants kinetics becomes more and more important and it is recommended to measure dynamic surface or interfacial tension.

The following methods can be used:

Static

Liquids - Du Noüy Ring Method

Liquids - Wilhelmy Plate Method

Liquids - Pendant Drop Method

Liquids - Spinning Drop Method

Dynamic

Liquids - Bubble Pressure Method

Liquids - Drop Volume Method

Foam formation, foam stability, efficiency of foaming agents, foam stabilizers or defoamers for both stable and short-live foams can be studied according to the dynamic decay model which describes drainage and breakdown separately.

The method is called:

Liquids - Dynamic Foam Analysis

Solids (Contact Angle)

Contact angle is an easily accessible and directly observable quantity which describes the wetting and dewetting behaviour of a liquid on a solid surface. The size of the contact angle is influenced by the surface tension of the liquid, the surface free energy of the solid and the interfacial tension which forms between the 2 phases. Contact angle data and surface free energy values are used as a basis for modification of either the substrate or liquid to improve wetting, spreading and/or adhesion. A variety of different methods are available for determination of contact angles of liquids against solid samples.
