Microwave sample preparation of asphalt samples for R&D and Q&C laboratories

20 Sept 2024

To accurately determine the composition of the elements in asphalt, it is essential that the sample be broken down into the smallest possible particles and completely digested with concentrated acid during sample preparation. Many microwave instruments have difficulty completely digesting these types of samples. Explore how ETHOS™ UP, a high-performance microwave digestion system, in conjunction with inductively coupled plasma atomic emission spectroscopy (ICP-AES), is able to completely digest these samples.

ETHOS UP high-performance microwave digestion system

Milestone

The new ETHOS™ UP is simply the most advanced yet easy to use system for microwave sample preparation we have ever manufactured. It offers a perfect integration between microwave hardware, user interface, digestion sensors and pressure vessels.  Microwave digestion oven ETHOS UP covers the whole range of samples from routine to high-end applications including US EPA method 3052 for sediments, soils and US EPA method.

Digestion and ExtractionDigestion and extraction apparatus are used in sample preparation to break down samples or extract organic or aqueous compounds from a solid. Digestion may be conducted via hot block, microwave or Kjeldahl digestion apparatus. Extraction systems typically involve solvent extraction and include Soxhlet, Randall or Twisselmann extraction methods.
