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

Applications of 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

What is ColdBlock Digestion?

ColdBlock™digestion is a revolutionary sample preparation technology that sets a new performance benchmark for digestion procedures. It is unique among acid digestion methods in that it employs both heating and cooling to deliver accurate and precise results without relying on potentially hazardous reagents. There are numerous benefits to this novel type of sample digestion technology,

How do Digesters Work?

Digestion is the process of breaking down substances into their basic constituents, typically by using reagents such as strong acids, alkalis, or enzymes. It causes the complex matrices of compounds to gradually decompose and separate into distinct elements of interest which can be further refined to be used as intermediate goods or purified for study.

What is Sample Digestion?

Understanding the elemental composition of sample materials can be difficult, if not impossible, without first converting them into a format that is compatible with specific modes of analysis. Optical Emissions Spectrometer and Mass Spectrometer systems, for example, can provide valuable insights into what elements are present in a myriad of different sample types; provided they

COLDBLOCK’S TECHNOLOGIES – Fast, safe and efficient sample digestion method

Headquartered in St. Catharines, Ontario, ColdBlock Technologies Inc. was founded in 2014 to develop their sample digestion technology initially for the mining industry. ColdBlock™ Digestion is an alternative to conventional technologies used by laboratories to determine precious and base metal concentrations in samples from their mining operations. ColdBlock™ Digestion is the only digestion technology that
