“As spectroscopic ellipsometry rapidly moved to the top of our list of required metrology for our development, Dr. Sun and his team at Ångstrom Sun Technologies provided our technical staff with strong technical support in the time leading up to our instrument purchase. When we decided to move ahead with acquisition of an Ångstrom Sun tool, Richard and his team met a very aggressive manufacturing and shipment schedule, which provided a tremendous benefit to us. And as we develop our own expertise in running the instrument, the Ångstrom Sun team continues to provide rapid, high-quality support for us. We’ve been very happy with our relationship with Ångstrom Sun and look forward to continuing to work with them.” by David Maloney, COO, Equity Solar, Inc.
Chromatography has developed into a highly sophisticated and varied procedure which is used in chemical or bio-processing industries; the need to separate and purify a product from a complex mixture is a very necessary and highly important step in the production line. The separation can be achieved with great precision; even very similar compounds, such as proteins that may only vary by a single amino acid, can be separated this way. In fact, chromatography can purify any soluble or volatile substance if the right adsorbent material, carrier material, and operating conditions are employed.
