Gel-Permeation Chromatography (GPC)

GPC performed using Waters 1515 Breeze system with refractive index detection. Used to determine molecular weight in ​the ​range of 400,000- ​500 Da, test sample compared to polystyrene standards ​ for determination of number average molecular weight, weight average molecular weight, polydispersity index, and other parameters as desired​. $1​00/sample.

 

Modulated Differential Scanning Calorimetry

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.

Rheometer

Rheometer

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.

Mechanical/Texture Analysis

Texture analyzer shown with tensile grips

Texture analyzer shown with

TA-96B: Miniature tensile grips

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.
