ColdBlock Digesters: Innovative Sample Preparation Technology

Digesters are instruments used to aid a chemist in sample preparation. They work by assisting in the decomposition of a solid sample into a liquid state to prepare them for various methods of analysis. Traditional digesters use varying forms of conductive/convective heat and strong acids, alkalis, or enzymes to achieve this. The combination of sample

Wet Chemistry Laboratory Digesters

Most analytical laboratories analyse a wide range of samples. The samples are received and go through a chain of custody where each step prepares them for analysis. One of the main ways to prepare a sample for analysis is that of wet chemistry. During this step, a sample is dissolved in a liquid which allows

Microwave Digestion Systems Vs. SWIR Digesters

Sample digestion is the process of decomposing solid samples into a more workable form, in this case a liquid state. It is a crucial intermediary step for elemental analysis of a wide range of sample types, including ash, cosmetics, minerals, pharmaceutical goods, and more. Typical sample digestion workflows involve dissolving samples in reagents such as

Types of Sample Digestion: A Brief Guide to FSWIR-Assisted Digesters

Understanding the elemental composition of sample materials requires converting them into a format compatible with a specific mode of analysis. Optical emission spectrometry (OES) and mass spectrometry (MS) systems can offer insights into the elements present in a variety of sample types. However, before this happens, they must be decomposed into a homogenous solution and

Soil Digestion: How Different Digesters Impact Trace Analysis

Carrying out soil analysis is a multi-step method, commencing with sample acquisition and ending with chemical analysis. These analytical workflows are designed to measure the mineral and nutrient levels in soils, to improve harvest yields, and to determine if fertilizer additions are necessary to restore mineral and nutrient imbalances. Quantifying levels of trace elements found

Metal Analysis: Which Digestion Method is Best?

Metals are extremely abundant, comprising almost three quarters of all naturally-occurring compounds on earth. Metals that are extracted from the earth tend to also be combined with one another to form alloys. These alloys, like carbon and stainless steels, are widely used as construction materials so accurate assessment of their composition is vital. On the

What is Soil Digestion?

Quantifying  trace elements present in sediments, soils, and brownfields is critical for a wide range of research areas. Carrying out an analysis of trace concentrations is a multi-step process that begins with sample acquisition and ends with analysis of its chemistry. While systems and instruments used in different workflows vary, a critical intermediary step for

Understanding Metal Digestion

Metals are compounds that are relatively abundant in our environment. There are different types of metals that have been grouped together as our understanding of them has evolved over time. One such group are the heavy metals like lead and cadmium, which are considered toxic. An excess of heavy metals in the body typically arises

Using Digesters for Environmental Analysis

There are various logistical barriers to environmental analysis. Let us use sediments and soils as an example. Soil contamination is a complex issue with far-reaching implications for human and environmental health. It concerns the pollution of land by both organic and inorganic contaminants, which can be detected and quantified using various chemical techniques coupled with
