New home of the Poznań Radiocarbon Laboratory


From the onset of July 2013 on, extended Poznań Radiocarbon Laboratory operates in a new location. Decision on the extension was induced by getting by the Adam Mickiewicz Uniwersity of grant to purchase a new AMS 14C spectrometer. In this issue  Foundation of the A. Mickiewicz University decided to construct a new building, allowing for installation of the new spectrometer and for extenstion of the Poznań Radiocarbon Laboratory. The new home is situated next to the building, where our lab has operated for 11 years.

In the new home, Radiocarbon Laboratory is equipped with lines for parallel preparation  of 30 samples (in the former home, there were 20 such lines).

... and next we have a large room for chemical preparaiton of samples.

Ultimately, our lab will posses lines for parallel preparation of 40 samples. This will allow us to increase our throughput and in future, should distinctly shorten our turnover time.



Moving the Laboratory to the new home
 
Decision on situating new home of the Laboratory, was reached by the Foundation at the end of 2011. The new, 3-floor building (E) of the Poznań Park of Science and Technology has been constructed in a very short period of 8 months, between March and November 2012.

The photographs below show the building "E" in March, April, June and September 2012.  prl_000.png

Rooms of the new home, on the first floor of building E", were put into operation at the end of 2012. A part of the main hall, with a specially concreted floor, has been devoted to space for the new 14C spectrometer, and after its installation, was encased with a glass wall.

Before moving the equipment from the old home, in the new hall we launched new lines for preparation of 10 samples.

Next, we were gradually moving the old vacuum lines from the old building, and installing them in the new home.



History

AMS 14C dating in Poznań started in mid-February 2002. Since that time, the number of samples dated per month was gradually increasing. Besides, we were continuously monitoring the  quality of our dating.

Since December 2003 the 14C dating unit consists of Poznań Radiocarbon Laboratory and AMS Laboratory. The new structure works as effectively as the former one, and the change does not alter the quality of our dating and the manner of our contact with the external customers.

In summer 2004, we extended our sample preparation lines. This expansion significantly increased our throughput and reduced our turnover time.

Installation of the new AMS spectrometer   

 

The new spectrometer "Compact Carbon AMS" ser. no. 012 arrived on 12 March 2013. It has been installed in the just constructed building "E" of the Poznań Park of Science and Technology, Foundation of the A. Mickiewicz University

The new spectrometer was installed and launched in the period of five weeks

After installing the spectrometer and encasing its room with a glass wall, we could start  moving the equipment of the Poznań Radiocarbon  Laboratory




Spots where our samples come from



 

  European projects

  Our center participates in three European projects:

millennium.png

Integrated Project: MILLENNIUM „European climate of the last millennium"

ecochange.png  
Integrated Project: ECOCHANGE “Challenges in assessing and forecasting biodiversity and ecosystem changes in Europe"
nice.png RTN NICE: „Network for Ice Sheet and Climate Evolution”






















The official partner in these projects is the Adam Mickiewicz University, and the tasks of the projects are realized by 14C AMS Laboratory

Our throughput

  The graph below shows the number of 14C dates obtained since the beginning of our activity.

Due to high throughput kept all the year, and small number of samples received in August 2017, our turnover time (time between sample's arrival to Poznan and age reporting) shortened considerably. Currently, this time is ca. 10-12 weeks.
