interFAce Measurement & Analysis System

Introduction of FAMAS
FAMAS – interFAce Measurement & Analysis System issoftware to measure and analyze surface phenomena ofsolid and liquid, and presents physical properties of Contact
Angleinstaticand
dynamicranges,
liquidsurface/interfacial tension, and surface free energy. It
performs by coupling with KYOWA’s contact angle meters.

Measurement Sheet Window
FAMAS adopts multiple-document interface.
Multiple measurement sheets can be displayed at
the same time in the base window, and eachmeasurement sheet can be liked with individual
parameter window (mentioned below). These
enable easy comparison of data between different
materials or conditions.
A measurement sheet is composed of 45 rows by
10 columns for data view.
Parameter window
Property window is visually almost same.

Parameter Window

A window to set up measurement conditions and parameters. Time functions, image threshold level, andalgorithm for analysis are available as parameters.
The window is also usable as a “test measurement” for temporary measurement or checking image
conditions.

Property Window
Measured image data, as well as numerical data, are saved and they can be confirmed and corrected on
this property window. The images can be displayed as a slide show.

Standard Functions & Features
Fast Image Capture, 30–2,700 FPSContinuous capturing of theimages and analyzing them ispossible. The frame rate isvaried from 30 to 2,700 fps
depending on the model and option.

Advancing & Receding Angles (DMo series and DMs-401 at option)
Hysteresis of drop advancing andreceding angles can be obtained byincreasing and decreasing captive
drop volume.

Advancing

Receding

Automatic Recognition of Drop Deposition
It allows measuring contact angle at a regular time after drop deposition.

Automatic Recognition of Drop Deposition
It allows measuring contact angle at a regular time after drop deposition.

Live Image & Focusing Aid
The image monitor displays the live image of the actual droplet, the values (dropletvolume, contact angle), and the signs to determine the results (fitting curve or points,baseline and tangent line). The focus aid is displayed with index graph and numericalvalue to eliminate personal error of focusing.

Threshold Level Adjustment
Threshold level to determine image binary can be adjusted
before and after measurement. Both relative and absoluteadjustments are possible to apply the optimized image analysis.

Graphing
Contact angle data versus time can be drawn on a graph.
Besides the contact angle, variable data as shown below arealso selected for graph data.

Variable Data Presentation
Besides contact angle, drop volume, absorbing amount, ratio of droplet remained
volume, droplet height and width are obtained.

Correction of Curvature
Data correction on a convex surface such as lens and tube (in cross section) ispossible by giving the radius of curvature.

Optional Add-in Software
Variegated functions as below software are available as the FAMAS add-in software.
Dynamic contact angle

Surface free energy[Extension & Contraction method]

Analyzes solid and liquidsurface free energy. Geometricmean, Harmonic mean, acidbase, Interaction analysis (workof adhesion, interfacial freeenergy), Young-Dupré, Zisman

Measures advancing/recedingangles by increase anddecrease of captive drop
volume.

Sliding angle
Obtains advancing/recedingangles under tilting solidbase. The base angle whendroplet gets sliding is definedas Sliding Angle.

Pendant drop
Measures surface/interfacial
tension of liquid samples bypendant drop method.
