Hello I got definition from page http://en.wikipedia.org/wiki/High-performance_liquid_chromatography High-performance liquid chromatography (HPLC; formerly referred to as high-pressure liquid chromatography), is a technique in analytical chemistry used to separate the components in a mixture...

actually I am mixing all inorganic compound in water then I want to know the quantity of each compound ? I did search , I don't have any Idea that HPLC , GC work to separate inorganic compound

Hello I need some ideas . there are about nine or ten compounds that are present in water [((H3BO3),Ca(No3)2),KNO3, KH2PO4), (K2SO4, (ZnSO4)]how to separate the compounds ? how to measure quantity of each ? I did google search , I got the HPLC , GC , spectroscopy , but I don't understand...

hello Thanks for help. plant does not absorb all nutrient very fast. I want to some lab test to measure amount of nutrient present in water but I don't know to test each nutrient ? Hydroponic nutrient sloutaion 1) Boric Acid (H3BO3): 0.028g 2) Calcium Nitrate (Ca(No3)2): 0.002 gm 3)...

Hello I need some help. I am making nutrient solution for plant. plant are growing in water without soil 1. MgSo4 0.65 gm 2. H3Bo3 0.30 gm 3.KH2So4 0.37 gm 4. K2So4 0.45 gm above 4 nutrients are mix in 1 L water . Plant will absorb all nutrients according their needs How to calculate that...

hello ; I need some help.I reading about TEM TE and TM Modes for Waveguides. actually I need some equations for Planar wave guide and optical fiber wave guide. I did google search. I don't understand how to write equation step by step for planar wave guide I found this link...

Hello , I need help , rom memory is memory that store program. we can only read rom memory. https://www.physicsforums.com/attachments/https://www.physicsforums.com/attachments/77060 look this diagram why does we connect both memory. I have read that when we start to read the program memory. we...

first of all thank you for your cooperation I am sharing my big doubt 8051 Instruction set 5 bit opcode + 3 bit register specification 7 bit opcode + 1 register specification 8 bit opcode 5 bit opcode that allow 32 operations 7 bit opcode that allow 128 oprations 8 bit opcode that allow 256...

I want to learn some basic then I will do my own design I have one zip file for mov instruction 5 bit opcode + 3 bit register specification 7 bit opcode + 1 register specification 8 bit opcode 5 bit opcode + 3 bit register specification MOV A, Rn MOV Rn, #immediate MOV Rn, direct MOV...

actually I want to make microcontroller on FPGA using verilog code I have written some verilog code for counter , alu decoder the code that i posted in my post is just sample code now I am trying to make some specification so I did some homework If you can check my work its very good for...

look at my another effort Instruction set opcode - instruction name operand - data or address 6 bit opcode +mode +5 bit source register + 6 bit for destination register Mode 0 address (without #) 1 number (with #) Opcode instruction mode example...

instruction set for this hypothetical microprocessor suppose we have 8 bit instruction first 4 bit for opcode and last 4 bit for register specification I have following component component ram memory A accumulator 4bit R1 resistor 4 bit ( R1 is temporary data storage register ) 4 bit opcode...

hello I need some help. I created one example to understand some basic component ram memory A accumulator 4bit R1 resistor 4 bit ( R1 is temporary data storage register ) Register memory address bus - 2 bits (RA0,1); Register memory data bus - 4 bits (RD0~3); Register memory read enable...

mov instruction = 0010 here I am using only one Instruction I am using 4 memory register and A accumulator for all operation Code (Text): opcode source destination data...

first I wanted to make decoder for microcontroller but now I want to learn how instruction set implement 8 bit instruction set 4 bit opcode + 2 bit source register +2 bit destination register+ 4 bit data accumulator A memory register R1 memory register R2 memory register R3 opcode...
