LiquidLINE Donation Campaign for the Baltic Sea is closed.

Thank you for contributing to our campaign to raise awareness of the over-fertilization of the Baltic Sea by sharing and liking our video. 

We have donate 300 to the WWF project "Save the Baltic Sea".

The Story Behind the Video

In Sweden we don't say a Drop in the Ocean, we say a Piss in Mississippi. 

During the spring of 2017, the OPSIS LiquidLINE did some research about measuring very low detection limits of nitrogen, in particular in waste water. During a lunch break at the office, someone realised that the detection limit of the LiquidLINE Kjeldahl analyzer is so low that it could measure a "piss in Mississippi". And so the idea to this video was born.

Why save the baltic sea.

Measuring Nitrogen in rivers and reducing over-fertilization is important. 

The Baltic Sea is part of the Atlantic Ocean, located in northern Europe. It has played an important role in trade, fishing and shipping as well as recreation. It is brackish, consists of both salty and sweet water, with an important biodiversity. 

During the last century, the Baltic Sea has degraded, due to climate change, over-fishing, and pollution which have led to over-fertilization. This has led to a chain reaction where the many animal and plant species are threatened. Characteristics for the Baltic Sea is that it is shallow with a restricted flow of water. This makes pollutives and toxics to remain easier in the sediment and organisms of the Baltic Sea, leading to a critical environment. 

It is important to stop the rising problems in the Baltic Sea. Many organisations are working on solutions, among others WWF. WWF has an on-going project with the aim to save the Baltic Sea.

How Precise is the KjelROC Analyzer?

The OPSIS LiquidLINE KjelROC range of analyzers offers innovative, precise and cost-efficient solutions for Digestion, Distillation, Titration and determination of protein according to the Kjeldahl method. 

Unique Predictive Titration gives several advantages in the lab such as superior measurement at low nitrogen levels. The possibility to send and receive results wirelessly, significantly reduces the integration and IT costs. A Digestion block with even and robust heating increases quality of analysis.

The Kjeldahl method (TKN) or Kjeldahl digestion is a method for the quantitative determination of organic nitrogen. This method was developed by Johan Kjeldahl in 1883 and is today the reference method to determine Protein in food and feed.
