A buffer amplifier of unity gain is generally used when you need to islolate the source.
Connecting a source to an amplifier, can have an affect on the original signal. A buffer amplifier stops the signal being affected by the subsequent amplifier sections. The input to the buffer is matched to the signal impedance.
Yes, in a 1:10 dilution of Na2CO3, and NaHCO3, the buffer capacity for basic solutions is 7E-4 and for acidic solutions, 1.2E-01
Buffer AL is used in DNA extraction and causes cell lysis to expose the DNA. Buffer AL is used during DNA isolation using QIAamp and DNeasy protocols. Buffer AL is stable for 1 year when stored closed at room temperature (15-25°C).

buffer systems function mainly to regulate the acid or base balance in the body. there are 3 principal classes of buffers in the body - proteins, phosphate buffer system and the bicarbonate buffer system. however, you are asking of the organs involved. these are the kidneys and the lungs.
Each buffer will only be of sufficient capacity within a pH interval of pKa+1 > pH > pKa-1 so the optimal buffer pH-range is maximum 2 units.

A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain

It will have a fixed gain of 1. It is known as a voltage follower or a unity gain buffer.
Smith Custom Amplifiers's population is 1.
10x to 1x is a 1:10 dilution Therefore, add 1 part buffer, 9 parts DI-water If 100uL is 10uL (1 part buffer) and 90uL (9 parts DI-water) Then, 200ul (100 x 2) is 20uL (1 part buffer) and 180uL (9 parts DI-water)
Do you mean with opamp circuits or tuned RF/IF amplifiers? In both cases several stages can be used to increase the gain. With opamp circuits though getting both wide bandwidth and high gain at the same time is difficult. With tuned RF/IF amplifiers two things can be done to get wide bandwidth: 1) reduce the Q of the tuned coupling transformers connecting the stages and 2) stagger the tuning of the tuned coupling transformers connecting the stages so that some are detuned high while others are detuned low.
AF means audio frequency. Audio Amplifiers can be subgrouped as voltage amplifiers (or pre-amplifiers) and power amplifiers. The voltage amplifier will raise the level of level of the output of a microphone from say 1 mV to 500mV or 1V. The power amplifier will be the interface between this and the load, which is a speaker. The resistance of the speaker is often 4 ohm or 8 ohm. You cannot have a speaker with 1k as resistance! As such to get say 8W output, an amplifier providing 8V will have to pump 1 amp into an 8 ohm speaker. Thus power amplifiers will have to drive a lot of current into the load. Voltage amplifiers cannot do this. A power amplifier sometimes just has unity voltage gain, but has ability to drive a lot of current into the load. Typical power amplifiers are operated in class B, where for 50% of the signal swing, one transistor provides current, and for the other 50%, the other transistor in a class B provides current into load. Class B amplifiers have cross over distortion, But this can be overcome by pre-biasing, or making the stage operate as class AB. The power amplifiers can also be used to power low resistance loads such as a step up transformer.

RBC-1 is for JX, Slash and older A and G series amplifiers, HD-RLC is for the new XD, M(Xd marine, and HD amplifiers. The cost is the same of $29 for both of them.
Difference between Amplifier and Repeater 1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain. 2. Repeater has an amplifier as a part of it. 3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.
