  1. The time of flight is proportional to the square root of the mass of the ions, showing that the lighter the ion the faster it will pass through and the quicker it will hit the detector. The heavier the ion, the slower it will travel and the longer it will take to hit the detector.

  2. Teaching notes: Time of flight mass spectrometry. These teaching notes relate to section 3.1.1.2 Mass numbers and isotopes of our AS and A-level Chemistry specifications (7404, 7405). This resource aims to provide background material for teachers preparing students for AS and A-level Chemistry. It is provided as an additional resource to cover ...

  3. 29 sie 2023 · The Time of Flight mass analyzer (TOF) is one of the most widely used mass analyzers in the mass spectrometric field. Similar to other mass analyzers, its main function is to separate charged particles formed by the ionization process.

  4. Graphing Linear Functions. Equation 1B.5.3 is a linear equation. y = mx + b y = m x + b. m is called the slope of the line, which is the ratio of the change in y (the rise) to the change in x (the run). Since the line is linear, the slope is the same between any two points along the line.

  5. 6 maj 2024 · The time of flight (ToF) sensor measures the distance between two points using the ToF principle using light or sound. A signal, usually light photons, is sent from the sensor's emitter to the target and then received back at the sensor receiver. The time taken by the signal helps measure the distance.

  6. the same, as is the case for rates graphs. Hence, when looking at a concentration-time graph we can tell when a system has reached equilibrium by the flat line of the concentration graphs. Here at T1 equilibrium has been reached. 2) A spike in the concentration of one of reactants or products indicates the addition of substance to the system and

  7. 11 sie 2022 · A chemical symbol is a one- or two-letter designation of an element. Some examples of chemical symbols are O for oxygen, Zn for zinc, and Fe for iron. The first letter of a symbol is always capitalized. If the symbol contains two letters, the second letter is lower case. The majority of elements have symbols that are based on their English names.
