Calculates serial dilution using initial concentration and dilution factor or a concentration range. Main applications include ELISA and other microplatebased experiments.

20210614· Project Portfolio Management (PPM) is a critical part of business planning that helps project managers measure the potential revenue of a future project before getting off the ground. Leveraging a PPM tool gives companies the data they need to put the pieces of a project together before making any risky decisions. Project portfolio management tools usually help strengthen general project ...

PPM stands for parts per million. It also is a measure of concentration, though it is often provided by gas meters. Step 1 Multiply the LEL percentage number by 10,000 to get PPM.

Calculators; Parts Per Million (ppm) Converter; Converter Parts Per Million (ppm) Parts Per Million (ppm) Converter for Gases. This converter calculates the measured value in units of [ppm] into units of [mg/m 3] and visa versa. The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the ...

20210810· Other uses of the parallel resistor calculator. The principle is the same as when determining capacitance in series or induction in parallel you can use it for these calculations too. Just remember that the units are not the same! If you would like to find out the value of power dissipated in the resistor, try the Ohm''s law calculator. Bogna Szyk and Álvaro Díez. Mode.

The following formula may be used to calculate a parallel resonant crystal''s external load capacitors: CL = ((CX1 x CX2) / (CX1 + CX2)) + Cstray where: CL = the crystal load capacitance Cstray = the stray capacitance in the oscillator circuit, which will normally be in the 2pF to 5pF range. Assuming that CX1=CX2 then the equation becomes: CL = ((CX1 x CX1) / (2 x CX1)) + Cstray CL = (CX1 / 2 ...

Calculators: Temperature Coefficient. Back to Calculator Index. This calculation arises when you need a part of a certain temperature coefficient, but you only have a limited selection of coefficients and values. A typical example would be, a radio tuning coil exhibits a +100 ppm/°C coefficient, thus requiring a 100 ppm/°C capacitor. But you only have on hand (or can order) N750 type ...
