The present disclosure provides for a system and method for rapid, accurate, and reliable targeting and interrogation of pharmaceutical samples. The chip has a first column of firing chambers and a second column of firing chambers in which each firing chamber comprises a heater and an ink channel. The particles are formed from molding techniques that can include high throughput and continuous particle molding. The rare earth component preferably includes cerium which enhances the sulfur reduction activity of the catalyst. The server receives collected user event data and sends an acknowledgement message to the client whereby indicating that the server received the user event data intact. The system typically has a nonlinear component that either saturates or produces distortion from the strong interferer, which is thereby reduced.
