Analytical Services

Our "Analytical Services" laboratory is glad to support you with analyses of:

  • Ready-to-drink beverages like fruit juices, flavoured milk, chocolate milk, soft drinks etc.
  • Food dressing, mayonnaise, catch-ups etc.    
  • Pharmaceutical products like ophthalmic suspensions, syrup, API etc. 
  • Cosmetic products, like, body lotions, sunscreen, shampoo, shaving creams, etc
  • Soap & detergents
  • Printing ink, Inkjet inks, paper, etc.
  • Industrial & decorative paints,
  • Lubricants & Oils
  • Fiber and fabrics
  • Surfactants & foams

 

*Chemical/physical analysis (e.g. Surface tension, contact angle, Surface free energy, wetting and spreading)

 

*Physical stability analysis (e.g. stability index, rate of sedimentation/ clarification and prediction of shelf life)  

 

Our analysis will help to develop your products much faster and you will save on investments and resources in the establishment and maintenance of your own laboratories, space and staff. The measurements can be performed under secrecy agreement.

 

Special offers available for academic institutions and research student

Surface Tensiometer

Measurement of Surface Tension and interfacial tension are performed using KRUSS K100 Force Tensiomter, Bubble Pressure tensiometer and Drop shape analysis system, Following test are performed:  

>Surface & Interfacial Tension by Wilhelmy Plate Method (viscosity of liquid less than 2000 mPa• s)

>Surface & Interfacial Tension by Du- Nouy Ring Method

>Surface & Interfacial Tension by Pendant Drop Method

>Critical Micelle Concentration Determinations (minimum of 40 concentrations studied)

>Determination of the Overall, Polar, and Dispersive Components of a Liquid Surface Tension(Fowkes method)

>Bubble Pressure Method - Surface Tension as a Function of Surface Age(Maximum surface age range is 5 milliseconds to 50 seconds,actual available range is sample dependent; density, andequilibrium surface tension are also reported for each sample.)

>Pendant Drop Method - Surface Tension as a Function of Surface Age(Surface age range is 1 second to equilibration;)

These measurements can be performed at room temp or set temp between -10
°C to 100°C

Contact Angle Measurement and Surface Free analysis

Following measurements are performed

1.Automated Goniometer Method Wetting Angles (Equilibrium advancing (wetting) angles are reported, using a single liquid, ten droplets measured.)

2.Automated Goniometer MethodDewetting Angles {Equilibriumreceding (dewetting) angles are reported, using a single liquid, ten droplets measured.}

3.Automated Goniometer Method Spreading Chararacteristics (Contact angle is reported as a function of time from the time of droplet placement until the contact angle equilibrates, using a single liquid; three droplets are studied)

4.Wilhelmy Method - Characterization of the Whole Surface (Advancing and receding angles are reported along with wetted length, using a single liquid; duplicate experiments performed. Note that the sample must be the same on both sides.)

5.Surface Energy – Fowkes Method (Equilibrium advancing contact angles are reported for two liquids Fowkes surface energy theory is used to determine overall, polar, and disperse components of the solid’s surface energy.)

Surface Energy – Other Methods (Priced per number of liquids studied for advancing contact angle, with application of relevant theories included.)

6.Washburn Sorption Method for Contact Angles (Results are capillary constant for the solid, and contact angle for a single liquid, duplicate tests. Viscosity, surface tension and density of the liquid used muAst be known.)

7.Automated Goniometer MethodAdsorption Characteristics (Contact angle data is collected asa function of time from the time of droplet placement to equilibration (typically 0°). The contact angles reported are "apparent" angles which characterize absorbency of the solid. For a single liquid, three droplets are measured.)

9.Washburn Sorption Method for Contact Angles (Results are capillary constants for "packed plugs" of the solid, and contact angles for a single liquid. Duplicate experiments are run. The viscosity, surface tension and density of the liquid used must be known.)

10.Automated Goniometer Method – Adsorption Characteristics (Contact angle data is collected asa function of time from the time of droplet placement to equilibration (typically 0°). The contact angles reported are "apparent" angles which characterize absorbency of the solid. For a single liquid, three droplets are measured.)

Dyanamic Surface Tension Measurement

Dynamic Surface tenson is measured by using Bubble Pressure Method

Surface Tension as a Function of Surface Age (Maximum surface age range is 5 milliseconds to 50 seconds,actual available range is sample dependent; density, andequilibrium surface tension are also reported for each sample.)

Dispersion Emulsion Stability Analysis

We offer following measurement using TURBISCAN - EXPERT unit

> Emulsion/ Suspension/ dispersion stability Short term 

>Emulsion/ Suspension/ dispersion stability Long term stability/ ageing study

    Applications:                           

   Home and Personal care: 

  • Emulsions, skin lotions , sun creams( in which detection of coalescence and creaming is faster then visual test).
  • Foundations, Nail varnish, lipsticks (Detection of sedimentation).
  • Bath additives, shampoo, shaving foam - a particular foaming and stability behavior are expected in each care sector.

Pharmaceuticals: Vaccines, Ophthalmic suspensions, Inhalers.(study of particles aggregation and sedimentation)

Paints and inks: Sedimentation, Aggregation, Redispersibility in paints and inks is detected that causes coating defects and printing faults.

Food:

  • Dairy products (particle size variation, creaming of fat droplets ,sedimentation of calcium or chocolate particles)
  • Soft drinks and fruit juices(ring formation, color change and pulp sedimentation)
  • Ice creams and deserts (detect destabilization phenomena of cream).

Oil and Petroleum:

  • The quality control tests and stability analyses of fuel oils, crude oils and drilling fluids   are done Using Turbiscan.
  • Using Turbiscan, we measure the efficiency of additives used for de-emulsification, the efficiency of dispersant on asphaltenes .

   Electronics:

  • Slurries homogeneity and stability can be checked.
  • Energy (solar cells, fuel cells, secondary battery)quality control and homogeneity of the inks coated to the cells.
  • Display (LCD, LED, e-papers)influence of additives on dispersion stability.
