Older videos

These video tutorials were recorded on a much earlier version of HSPiP. However, they still give a good feel for the sorts of things that HSPiP can do. A glance at the range of videos is a good reminder at how versatile HSPiP is!

Calculating the basic HSP Sphere

How to take the solubility data in a range of solvents and calculate the HSP sphere position and radius – with one click of a mouse. The Basic Sphere.wmv

Getting started

How do you go about measuring the HSP of your first polymer, pigment or nanoparticle? Getting Started.wmv

HSP and Polymers

How to use the big database of polymers to explore interactions of polymers with solvents and with each other. Polymers.wmv

Lots and lots of data

You need data to use HSPiP. We’ve provided lots of it (10,000 chemicals) – and made it convenient for you to incorporate it in your own work. Solvent Data.wmv

Solvent optimization

How the software makes it easy to find an optimum solvent blend to match a particular HSP target. Optimizer.wmv

Solvent mixture evaporation

How the software makes it easy to see how the different solvents in a blend evaporate at different rates and therefore how the HSP change during drying. There is a large database of RER (Relative Evaporation Rates) provided with the package. The modeller can include Activity Coefficient effects (themselves calculated using HSP!) and temperature effects of the HSP (see the tutorial below) and change in RER (using a large database of Antoine Coefficients included with the package).

Do It Yourself HSP

How the software gives you many ways to produce your own HSP values, including the classic Hoy and Van Krevelen methods (which are not recommended due to more recent developments) along with the latest Stefanis-Panayiotou (2008) method, and the Yamamoto Molecular Breaking method (Y-MB) for polymers as well. DIY.wmv

The following two links show the fully automated Y-MB method in operation for chemicals and for polymers: Automatic HSP.wmv and Automatic Polymer HSP.wmv

Utilities

HSE Read-Across

Making smart HSE (Health, Safety & Environment) decisions often depends on the ability to “read across” from the properties of a known molecule to those of an unknown. HSPiP makes this easy to do by producing a side-by-side comparison of chemical, functional, vapour pressure and solubility data. HSE Read Across.wmv

HPLC

IGC

GC and NMR

HSPiP can predict GCRI (Gas Chromatography Retention Indices) to give you predictions of where molecules will elute. And if you need to find the right deuterated solvent for your NMR experiments, the Solvent Optimizer comes to your rescue with a list of the commonly available deuterated solvents. GC and NMR.wmv

Diffusion modeller A brief taste of the powerful diffusion modeller that handles the full complexity of absorption and desorption of solvents into polymers. Diffusion.wmv

Temperature effects

HSP are defined at 25ºC. If you do experiments at other temperatures you want to know what the HSP values are at those temperatures. The program lets you do this very easily, using a database of thermal expansion coefficient values to calculate the changes according to the well-known Hansen & Beerbower formulae. Temperatures.wmv

Teas plot

Some people find the Teas plot useful (though we strongly recommend against using it because it happens to have no scientific validity and with modern graphics we don't need to condense things down into a ternary diagram). We’ve added the capability if it’s important to you. Teas Plot.wmv
