C400d Nebulizer

The Savillex C-Flow 400d (C400d) PFA concentric nebulizer combines the reliability of a low flow glass concentric nebulizer with the chemical resistance and low elemental background of a PFA concentric nebulizer. In addition, its unique constant diameter capillary and removable uptake line with zero dead volume connector give the C400d excellent resistance to clogging and extremely fast washout.

While microconcentric (uptake rate 200μL/min or less) PFA nebulizers are used as standard with ICP-MS for semiconductor applications, most non-semiconductor ICP-MS labs use low flow glass nebulizers due to their more suitable uptake rate and relatively low cost. The Savillex C400d was designed specifically for non-semiconductor ICP-MS use and while it can free aspirate, it is designed to be pumped and is optimised for the typical uptake rates (350-400μL/min) of today’s ICP-MS systems.

Moulded from high purity virgin PFA, the C400d offers the chemical resistance and low metal background of a conventional PFA nebulizer, but with several unique features. Its two-piece precision moulded design allows precise optimisation of back pressure during manufacture, ensuring consistently high performance. It also features an inner body that supports the capillary all the way to the tip, making it more robust and giving it a longer lifetime compared to other PFA nebulizers.

The C400d is optimized for use at 1SLPM to match the carrier gas flow rates of all common ICP-MS, and it’s 6 mm OD body fits all common spray chamber end caps. An 80 cm long uptake line is included.

The C400d is also extremely resistant to clogging by particulates: inside the nebulizer body, a constant ID capillary avoids the changes in ID that cause potential blockage points, and because the capillary is supported at the tip, the C400d can be easily and safely backflushed – without the need for tools.

The C400d is capable of handling over 15% total dissolved solids (TDS). The removable sample uptake line connects to the body using Savillex’s unique zero dead volume connector for reliable, reproducible connections and the fastest possible washout. A threaded PFA gas inlet fitting ensures a reliable, leak-free carrier gas connection and includes a range of adapters to connect to common gas line sizes.

Along with the C700d nebulizer for ICP-OES, the C400d makes up Savillex’s d-type (removable uptake line) nebulizer range. Like all Savillex nebulizers, d-type nebulizers are designed, moulded and assembled by Savillex, and the design of the d-type range has enabled a significant reduction in assembly time and subsequent cost reductions. As a result, Savillex d-type nebulizers offer all the benefits of PFA nebulizers and more - all at a price comparable to low flow glass nebulizers.

Combining high performance and ruggedness with fast washout, high matrix tolerance, chemical inertness and long lifetime, the C400d is the perfect choice for routine, non-semiconductor ICP-MS applications.
