The concept of “lean thinking” is applied with increasing frequency in a number of industries, including biopharmaceutical manufacturing, to eliminate waste and optimize workflow. Lean thinking refers to focusing on standardizing processes within workplaces to minimize redundancies and improve value. Safety also is important to every workplace, especially in biopharmaceutical manufacturing because it uses process chemical ingredients. By embedding attention to safety into the practice of lean manufacturing, companies can improve employee buy-in of lean initiatives while reinforcing the importance of safe practices. This combined philosophy allows companies to improve both workplace safety and efficiency.

Now that Avantor has implemented a new ERP system in the U.S., there are two easy ways to access Material Safety Data Sheets (MSDSs) electronically: 1) MSDSs are available 24/7/365 at AvantorMaterials.com 2) Provide an e-mail address and we will send you an MSDS as your product is being shipped (you will receive an MSDS the first time you purchase a particular product in a 12-month period or if the MSDS undergoes a substantive change). Let us know who should receive electronic MSDSs. Visit www.AvantorMaterials.com/MSDS-form.aspx and complete the brief form. If you do not have Internet access or an e-mail address on file with Avantor, you can call Avantor’s Customer Service Department at any time to obtain an MSDS. Contact Customer Service at (610) 573-2600 (option 2).

对于抗生素类兽药残留的检测，其他氨基糖苷类的检测，用到CBX小柱（500mg/6ml）7217-06进行样品前处理，之后通过LC/MS检测，得到了良好的分析效果。 Rapid screening tests can be used as part of an efficient program designed to monitor veterinary drug residues in cattle. In this work, three rapid tests designed to screen samples for the presence of antibiotic residues, the Fast Antimicrobial Screen Test (FAST), Premi® and Kidney InhibitionSwab (KISTM) tests,were compared using beef kidney juice and serum samples. In order to provide a realistic assessment, potentially incurred samples of beef kidney juice and serum were obtained from 235 carcasses which had been retained by inspectors in a processing plant for further testing. In addition, liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis was conducted on these samples to identify what antibiotics were present, if any, and their levels. The comparison of the three rapid screening test results with those from LC–MS/MS analysis allowed for a more complete comparison of the relative sensitivity of these analytical methods, as well as valuable information on false positive and negative response rates.
