COST SAVINGS AND GREEN INITIATIVES

Green Analytical Chemistry – The SIGNIFICANCE Mnemonic

Automated sample preparation can provide the following benefits under the SIGNIFICANCE scheme:

• Integrating analytical processes and operations.
• Implementing automation and miniaturization of methods.
• Increasing safety for the operator.
• Noting that the sample number and size should be minimal.

In-line trapping adds to the general automated sample preparation advantages

Generating as little waste as possible, and is particularly suited to miniaturizing methods.

Choosing Particle Size for SPE

Unsure which particle size to choose for SPE?
The standard (30-80 µm or no diameter listed) particles are good for most samples.
Smaller or larger particles are available for certain tricky sample types.
