IMPORTANT MESSAGE
Like many other companies and institutions around the world, we are experiencing interference with some of our systems within the TNT network.
We are implementing remediation steps as quickly as possible. We have implemented operational contingencies to continue to complete collections from customers with scheduled stops. For customers who do not have a regular stop, collection should be arranged via our customer service centers.
Customers may experience delays in the transit of shipments, particularly inter-continental or non-EU European delivery, as we work to remediate our systems. Additionally, if customers do not have the facility for self-labeling, they may also experience delays.
We are not able to collect shipments of dangerous goods at this time.
We regret any inconvenience to our customers.
Trace Impurity Identification using Q-TOF Mass Spectroscopy
Trace Impurity Identification using Q-TOF Mass Spectroscopy
Accurate Mass Spectrometry (MS) techniques are ideally suited to aid in the structural elucidation of trace impurities. A rapid approach used for the isolation and characterisation of trace impurities in drug substances and formulated drug products has been developed. The approach has been successfully employed for the characterisation of impurities from different substances covering a wide variety of structural classes.
