The IonPac® AS25 anion-exchange hydroxide selective column is a high capacity column designed for gradient separation of multivalent anions and polarizable anions (iodide and perchlorate) including sulphur species (sulphite, sulphate, thiocyanate and thiosulphate). The column simplifies the determination of polarizable anions by using an isocratic hydroxide eluent with no solvent required for the separation. Analysis time is approximately 30 minutes. The key application is sulphur speciation in complex sample matrices including food and beverage samples. The elimination of solvents reduces waste disposal costs and allows the customer to use RFIC-EG technology for this application. The column is available in 4 × 250 mm, 2 × 250 mm and 0.4 × 250 mm formats supporting flow rates from 0.010 to 3 mL/min. Capillary and microbore formats provide low eluent consumption and improved sensitivity.

Cooked ham, cured meat, pork, poultry and beef products are traditional meat classics. Due to their low fat content, cooked ham products also meet the dietary demands of increasingly health-conscious consumers. Nowadays, more and more attention is being paid to both quality and ingredients when meat and sausages are served. With its latest generation of injection brines for trade and industry, RAPS has committed itself to the further development of concepts that are as clean, sustainable and functionally convincing as possible. In addition to products for organic cooked ham, a specific VLOG-approved injection brine has also been developed for the industry (VLOG = certified GMO-free according to the German VLOG “ohne Gentechnik” production and certification standard).

Food manufacturers need to ensure that the cleanliness of their production lines is maintained to the highest standard to avoid contamination of product. Aseptic drives are carefully designed for applications where regular washdowns are required to maintain a clean environment. The motor is designed so that a fan and cooling ribs are not required, thereby allowing for a completely smooth outer casing with a non-drive end which is sealed. This eliminates any dirt traps on the motor casing and also prevents re-infection of the local environment caused by air movement from a cooling fan. The design also includes a very high level of ingress protection, up to IP69K, which is a special designation for washdown applications involving high pressure, high temperature water. In addition, the aseptic drive is painted using an acid and alkali resistant formula, which can withstand chemicals with a pH range of 2 – 12. As a result the new drive system can withstand the cleansing solutions and disinfectants that are commonly used within the food industry without affecting its performance. A combination of aseptic motor/gearbox packages has been developed with variable frequency drives (VFDs) to enable a very efficient package to be installed. The majority of the drives use 0.75kW motors, with some smaller 0.55kW units and most of these, nearly 80%, are coupled to the BK20 hollow shaft bevel gearboxes. When installing a large number of motors onto a production line, it is important to maintain high energy efficiency so that the return on investment can be minimized. All of the aseptic motors from Bauer are rated IE3 energy efficiency class and when combined with the VFD they can deliver optimum energy consumption and running costs. By designing a system with a large number of common components, the engineers were also able to minimize the spare parts inventory while still ensuring the most energy efficient and reliable design. In addition to this, the motor itself is equipped with thermistors and class F insulation, which makes it suitable for control by VFD and the thermistor connections are combined with the motor connections in a stainless steel, round connector which allows quick and simple motor connection while still maintaining the hygienic aspect of the design.
