Case Study Determination of cyanide and nitrogen Customer: Supplier of APIs, India

Case Study
Determination of cyanide and nitrogen
Customer: Supplier of APIs, India
The customer is one of the world’s largest manufacturers and suppliers of active pharmaceutical ingredients (APIs) for a wide range of therapeutic categories, including antibacterials, central
nervous system agents, antihistamines, anti-asthmatics, cardiovasculars, antivirals, antidiabetics, antifungals, proton pump inhibitors and pain management drugs. The laboratories are located in Hyderabad, India.
Application: Determination of nitrogen and cyanide in waste
water
The KjelFlex K-360 is used to determine total nitrogen in soil, fertilizer and plants. IR digestion
shortens total analysis time, and the modular design of the K-360 makes operation more flexible. The throughput in one day has been increased, and urgent results can be obtained in half
a day.
Equipment: Digestion Unit K-424 and Distillation Unit K-355
The customer works with non-Kjeldahl applications such as cyanide from hazardous samples. They
considered both Foss & BUCHI systems, but Foss does not have an acid-resistant pump. Also
we have a 300 ml tube for estimation of low nitrogen levels.
Benefit / Conclusion: Unprecedented speed
“The instrument is very convenient to use, and the results are reproducible in all the runs.”

The Digestion Unit K-424 is very useful because IR digestion provides results very quickly.
The Distillation Unit K-355 is very useful for Kjeldahl & non-Kjeldahl applications due to its acidresistant pump.
