Markelov HS9000

 Residual Solvents and other Organic Volatile Impurities (OVIs) are the result of the manufacturing process of drug products. In an effort to protect the health of patients, pharmaceutical manufacturing facilities must monitor the presence and concentration of these potentially harmful chemicals in accordance with the

International Conference on Harmonization (ICH). The ICH regulates the daily exposure concentration limits of these solvents. As a result of newly published toxicity data, these exposure limits have been reduced over the past several years. As the trend for lower levels of detection continues, the sensitivity improvements gained from the Dynamic Headspace sampling technique make the HS9000 an invaluable tool for the Quality Control Pharmaceutical laboratory.

LC241 HPLC Autosampler

 

The new LC-241 PLUS was designed as a low cost routine HPLC sampling system. The LC-241 PLUS can perform unattended repetitive automatic sampling as well as fast and simple single sample injections. Easy-to-use operation is accomplished through a clearly marked keypad along with menu driven options displayed on the back lighted LCD display. The optional drop counter allows independence from varying sample viscosities by determining the amount of sample flow-ing through the sample loop based on the number of drops rather than time. Easy  access from the top side of the LC-241 PLUS provides for easy maintenance and service of the sampling valve and probe needle assembly. Why buy more capability than you need? For basic routine HPLC sampling with workhorse performance the LC-241 PLUS is your choice.
