Buffer capacity of a buffered solution represents the amount of protons or hydroxide ions the buffer can absorb without a significant change in pH. To find the pH easily the Henderson-Hasselbalch equation can be used:ĭ. If you know the ratio of acid to base and both amounts are large the proton concentration can easily be found using the equation: When hydroxide ions are added to a buffer solution they react with the acid and are replaced by the Anions.Ĭ. Buffered solutions are simply solutions of weak acids or bases containing a common ion. A buffered solution is one that resists a change in its pH when either hydroxide ions or protons are added. The shift in equilibrium position that occurs because of the addition of an ion already involved in the equilibrium reaction is called the common ion effect.ī. When a weak acid solution has common ions added by a salt, the equilibrium will shift by Le Chatelier's principle. Thanks to the good and flexible interaction of all the companies involved, we were able to test everyone quickly and efficiently.A. The quick testing campaign also gives families a bit of security", says Rainer Wittenfeld, managing director of PCF.Ĭhemlab managing director Harald Störk is satisfied with the move: "Conducting the tests during ongoing shift operations was a logistical challenge that we were able to successfully overcome in a joint action with the freight handlers. This presence at the workplace is unavoidable and we need to protect our employees as best we can. "The staff of operational logistics has no opportunity to take advantage of home office protection. The Perishable Center Frankfurt (PCF), Europe's largest air cargo hub for perishable goods, is also participating in the test campaign. The protection of our employees has top priority for us, which is why we strongly supported the testing initiative." Through consistent implementation, we comprehensively protect our personnel. Nina Strippel, site manager and COO at LUG aircargo handling, agrees: "We established a crisis team in the company at an early stage, which consulted frequently and initiated measures adapted to the respective situation. As one of the largest cargo handlers at Frankfurt Airport, we must maintain our operational logistics processes for air cargo handling at all times." Especially after the holidays, we want our employees to be able to return to work with a good and safe feeling. The health of our employees is also a main concern for our shareholders WFS Worldwide Flight Services and Fraport AG. Even in times with lower public case numbers, we have paid strong attention to compliance with the mask requirement and our hygiene concepts. The staff is on duty around the clock to keep goods moving safely and quickly during the current crisis.įor Claus Wagner, managing director of FCS, the measure is another step forward in the company's infection protection concept: "The WFS Group, to which FCS belongs, has worldwide taken consistent protective measures since the beginning of the pandemic. This is primarily due to the high volumes of imported personal protective equipment. The employees of FCS Frankfurt Cargo Services and LUG aircargo handling moved up to three times more cargo. Despite the cancellation of the biggest part of passenger flights, Frankfurt Airport recently handled far more cargo than in the previous year. The aim of the measure is to ensure even better protection of the workforce against infection in the company.ĭue to the ongoing pandemic, the personnel involved in cargo handling is experiencing a major challenge. Over several days, the Bensheim-based company Chemlab conducted the tests on site. A total of around 1,500 employees of the companies, which together handle around 40 percent of the air freight at Frankfurt Airport, was tested. In the first week of January, a large-scale Corona testing campaign was conducted at Frankfurt Airport by the three major air cargo handling companies FCS Frankfurt Cargo Services, LUG aircargo handling and Perishable Center Frankfurt (PCF).
