| Orthogonal-flow sprayer with pneumatic nebulizer |
Enhances sensitivity across a wide range of LC conditions and reduces maintenance requirements. |
| High-capacity solvent drying system |
Reduces chemical noise and permits the analysis of thermally-sensitive compounds through user control of gas flow rate and gas temperature. |
| Dielectric platinum-plated capillary |
Enhances sensitivity, permits independent optimization of the spray chamber and ion optics, and allows dynamic optimization of in-source fragmentation. |
| Air-cooled turbomolecular pump |
Provides fast startup and a small footprint, and eliminates the need for cooling water. Single, split-flow turbo pump enhances performance and increases reliability. |
| Fraction collection capability |
Can monitor and trigger the collection of fractions based on mass, an analog signal input, or time. For mass-based determination, up to 16 m/z values can be monitored. Requires optional I/O Accessory Module. |

When using the Multimode source in APCI mode, the sensitivity is 50:1 RMS
(10:1 peak-to-peak). In mixed mode operation a test mix at installation will provide
no less than 20 % of the response obtained with dedicated sources.
