TransChem – the software that gets more knowledge from your data

TransChem is Transpec’s multivariate statistical analysis (MVSA) package that provides the tools to analyse your data, build measurement models and automate measurements. It has user friendly interface designed to extract more knowledge from your data.

MVSA uses every spectral data point in each spectrum acquired from a group of samples to describe and quantify the variance within the group. This variance can be described by a set of independent orthogonal principal components (PCs) which capture the variance of a single spectrum relative to the group and enable similarities and differences to be described and mapped in PC space (each PC may form an axis in a 2D, 3D or nD plot depending on the number of PCs required to describe the variance) and cluster plots may be used to define common groups. This is valuable as a rapid QA tool.

Physical property and performance data can also be regressed against the PCs and linear regression models established to relate physical properties to the spectral response and variations in that response. This is described mathematically by a series of regression coefficients that define the relationship. These coefficients can be used to relate spectral features (linked to the underlying chemistry) to the property of interest enabling causative relationships to be seen and further investigated.

TransChem Package

Chemometrics/MVSA

  • Very powerful statistical analysis
  • Use all the spectral information – not just known peaks, or overlay fits
  • Regress all the spectral information to properties of interest
  • Build a model
  • Make measurement predictions

Types of analysis

  • Analyse:
    • Qualification - identificationTSAN01 - Application notes 10/12
    • Quantification – concentration
    • Consistency – homogeneity & uniformity - dispersion
  • Predict:
    • Processing properties – MFI, liquid viscosity 
    • Thermal properties – glass transition, melting point 
    • Physical properties – density, mechanical modulus and strength, impact strength
    • Fire properties – UL scores, LOI
