Regions most interested in Spectroscopy this year

If you like to take your work on holiday, there are some exotic locations with a budding spectroscopic appeal. 



It seems Ethiopia, China and India are among those searching for spectroscopy-related subjects the most, according to Google Trends.

Ethiopia is testing soil in its highlands

According to an study articled in ISRN Soil Science and available on Hindawi, Article 92 of Ethiopa's constitution states how committed to "environmental protection, rehabilitation and sustainable land management" the country is.

The Growth and Transformation Plan II is a major force in the government's initiative to improve the efficiency of Ethiopia's agricultural sector by achieving an "annual real GDP growth rate of 11 percent." 

Two of the nine Strategic Pillars of the GTP particularly resonate with the country's potential need for spectroscopic quality-checking equipment and expertise:

  • "Increase productive capacity and efficiency to reach the economy's productive possibility frontier through rapidly improving quality, productivity and competitiveness of productive sectors (agriculture and manufacturing industries)."
  • "Building climate resilient green economy."

In the study from ISRN Soil Science, "soil spectroscopy was applied for predicting soil organic carbon (SOC) in the highlands of Ethiopia."

The samples came from the country's National Soil Testing Centre and from direct field sampling. Study sites included Mekele and the eery Bale Mountains.

According to the article, "soil spectroscopy is an effective method for predicting soil organic carbon."

Our Golden Gate ATR spectrometer accessory (heated option) was used to analyze soil at various temperatures.

China is testing vinegar

Ethiopa were the top searcher for the term "spectroscopy." But China are top of the pile when looking at regions with the most interest in the field of study overall (searching related terms that don't necessarily include the word "spectroscopy").

We discussed the increase in food safety-testing in fast-developing countries such as China and India in a previous article. On another food-related topic, is apparent that China, like Ethiopia, are increasingly carrying out their agricultural soil analysis using Spectroscopy.

Another application of spectroscopy in the Chinese market that becomes apparent after a brief online search is distinguishing Chinese vinegars.


Being similar in aroma and appearance, Chinese vinegars are difficult to discriminate by brand. China's Beijing Academy of Agriculture and Forensic Sciences carried out a study in which they observed the spectral aspects of alcohols, acids, esters and furfural in the vinegars.

In another study, Jinmei Wang et al classified Chinese tea leaves using laser-induced spectroscopy.

The Pearl FTIR transmission spectrometer accessory is ideal for the analysis of edible liquids. Read about analyzing milk using the spectrometer accessory.

Analying India's rich heritage

Top of the list of regions most interested in the topic of "Infrared Spectroscopy" is India.

The country's scientific sector is definitely growing healthily, producing more papers per person than the global average.

Palaeontology and archaeology appear to be two of the country's budding area's of research and analysis. In March this year the Ellora Caves in Maharashtra delivered new secrets to a team of scientists.

A Unesco World Heritage Site, the 34 caves were excavated out of the Charandri hills by Hindus, Buddhists and Jainists between the 5th and 10th centuries. By using IR spectroscopy, specialists discovered a mixture of hemp, lime and clay in the plaster which has so-well preserved the details of ancient drawings and carvings.

Elsewhere in Kaushambi, Indian archeologists used spectroscopy to prove that the Ghositarama Monastery had been a major producer of copper goods.

You can also read about how spectroscopy can potentially analyze different foodstuffs for contaminants here. In India, police found spices were being contaminated with toxic chemicals such as varnish, paint and glue to make them more attractive to buyers.
