Fourier-Transform Infra-Red Spectrophotometry

FTIR (Nicolete Protege model 460 E.S.P.)

FTIR analysis of organic samples elucidates the kinds of chemical bonds present in the molecule based on their absorbance spectrum in the infra-red region.

Sample capable of solvent casting/placement on KBr plate - $25/sample (bulk discounts available)


UV/Vis Spectrophotometry

Thermo Genesys 10S UV-Vis spectrophotometer

Soluble sample full spectrum 190-900nm against solvent blank - $5/sample (bulk discounts available)

Modulated Differential Scanning Calorimetry

Modulated DSC analysis available from PolySciTech using a TA instruments Q2000 instrument operating under argon purge and controlled using a Discovery Refrigerated Cooling System - RCS90. This allows for testing samples in the range between -90 C to 550 C. Modulated DSC allows for collecting not just heat flow of the sample but also the reverse heat flow which is related to analysis of complex mixtures and multiple transitions.

Mechanical/Texture Analysis

PolySciTech® offers texture analysis via a Texture Technologies Corporation TA.XTplus. The current configuration utilizes a 5 kg load cell for extreme sensitivity with soft and elastic materials. The testing arm can be equipped with either tensile grips for tensile testing or a ¼ inch steel ball/half inch dacron cylinder for compressive testing.

Typical mechanical tests include elastic modulus from 0-2% strain, stress relaxation (a.k.a. creep) as percent decline in force over 60 seconds of being held at a constant strain, elongation to break, yield stress. Akina can custom design tests to your specifications as well as perform textural tests such as crispiness and firmness. Below are elastic modulus and stress relaxation of some common food ingredients.

Item Elasticity (kPa/%) Stress Relaxation (%)
Marshmallow - (Great Value) 0.6 ± 0.1 38.3 ± 1.8
Gummi Worm - (Great Value) 0.7 ± 0.2 46.2 ± 2.8
Gum - (Ice Breakers "Ice Cubes") 29.9 ± 7.7+ 10.0 ± 1.5
Crouton - (Rothbury Farms) 36.6 ± 10.4 63.4 ± 14.1
Sugar Cube - (Domino) 112.0 ± 12.1 NA*
+ Gum coated with hard sugar coating
*Sugar cube could not be compressed to 20%

Mechanical analysis can be performed using texture exponent software allowing for mechanical as well as textural properties to be quantified.

Wyatt DynaPro NanoStar dynamic light scattering (DLS)

Instrument collects both static and dynamic light scattering signals for robust data. Commonly used used for the analysis of proteins, inhibitors, micelles, quantum dots, liposomes, metallic nanoparticles and more. Available to assay in either water or a wide variety of organic solvents.

Typical assay $50/sample. If a sample requires support assays for data interpretation (refractive index or viscosity) these will be billed separately as stand alone assays.

Rheometric Analysis

Rheometric tests can be performed at Akina, Inc. utilizing an AR550 (TA Instruments) Rheometer in the temperature range of ambient to 150°C.

This peltier controlled rheometer has both a 20 and an 8 mm attachment for viscosities ranging from water to viscous polymer melts. Rheometer can do both basic viscosity as well as oscillation measurements with continous or stepped sweeps of temperature, frequency, stress, as well as other variables. G',G", Delta and other rheometric variables are collected in oscillation mode. Rheological as well as molecular information about the material can be gleaned from this data.

Rheometric data can be analyzed on Rheology Advantage Data Analysis software.
