Abstract
A curtain chamber includes an orifice plate defining an orifice plate bore. A curtain plate is disposed adjacent to the orifice plate and defines a curtain plate bore. The orifice plate bore is disposed adjacent the curtain plate bore. A biasing element includes a first portion disposed in the orifice plate bore and a second portion disposed in the curtain plate bore. The biasing element biases the curtain plate towards the orifice plate. A race is defined by at least one of the orifice plate and the curtain plate. The race defines a race depth. A seal is disposed in the race. The seal includes an uncompressed seal depth greater than the race depth and a compressed seal depth less than the uncompressed seal depth.
Claims20
A curtain chamber comprising:
- an orifice plate defining an orifice plate bore;
- a curtain plate disposed adjacent to the orifice plate and defining a curtain plate bore, wherein the orifice plate bore is disposed adjacent the curtain plate bore;
- a biasing element comprising a first portion disposed in the orifice plate bore and a second portion disposed in the curtain plate bore, wherein the biasing element biases the curtain plate towards the orifice plate;
- a race defined by at least one of the orifice plate and the curtain plate, and wherein the race defines a race depth;
- and
- a seal disposed in the race and wherein the seal comprises an uncompressed seal depth greater than the race depth and a compressed seal depth less than the uncompressed seal depth.
A method of manufacturing a curtain chamber, the method comprising:
- providing an orifice plate;
- providing a curtain plate;
- disposing a seal into at least one of the orifice plate and the curtain plate;
- disposing a spring-loaded biasing element into at least one of the orifice plate and the curtain plate;
- disposing the curtain plate adjacent the orifice plate to engage the spring-loaded biasing element with a detent defined by an opposing surface of at least one of the orifice plate and the curtain plate;
- and
- compressing the seal between the orifice plate and the curtain plate, wherein compressing the seal configured the curtain chamber in an operational condition.
A mass analysis system comprising a curtain chamber comprising:
- an orifice plate;
- a curtain plate screwlessly engaged with the orifice plate, and wherein when the orifice plate is screwlessly engaged with the curtain plate, the mass analysis system is in an operational condition;
- and
- a seal disposed in a race defined by at least one of the orifice plate and the curtain plate, wherein the seal contacts both of the orifice plate and the curtain plate, wherein when the seal is compressed against both the orifice plate and the curtain plate, the mass analysis system is in an operational condition.
