The AMD2000 is a novel dilution system for use with many types of chemical analysis. Concentrated samples often require dilution to bring them within an analysers range. Manual dilution is error-prone and time-consuming, but automatic dilution can introduce delays and complications. This is because it has previously relied on a type of dilution in which the specimen is mixed with diluent to form a further sample. The patented design of the AMD2000 provides true in-line dilution without the creation of a secondary sample. The dilutor depends upon injecting sample at a variable, but accurately controlled rate into a stream of diluent. The secret of the device’s success lies in the patented injection valve that virtually eliminates carry over. The AMD has a keypad, an alphanumeric liquid crystal display and an RS232 port for connection to a PC or thermal printer. In manual mode it is operated using a system of menus selected via the keypad and will function with different types of automatic sampler. |
