Introduction
In clinical chemistry research facilities, glucose standards are essential for calibrating and controlling glucose measurements in Diagnostic Labs. A glucose standard with a realized focus is used to affirm the precision and exactness of glucose assessments in Diagnostic Labs. In this guide, we'll show you how to plan a glucose standard with a concentration of 100 mg/dL (5.6 mmol/L) step by step. This standard can be utilized as a reference fabric for glucose measures, guaranteeing dependable and precise results in heath care and Diagnostic Labs.
Materials and Reagents
Materials
- 100 mL volumetric flask
- Distilled water
- Analytical balance
- Pipettes of 10 and 1 mL each
- Glucose powder (C6H12O6, sub-atomic weight 180.16 g/mol)
- Label and marker for labeling the flask
Reagents
- Glucose powder (C6H12O6)
- Distilled water
Standard Preparation
Calculation steps to prepare a glucose standard (100 mg/dL (5.6 mmol/L)
Step 1: Calculate the sum of glucose needed
Desired concentration: 100 mg/dL
- Volume of standard: Please see Table 5 where it suggests planning for 100 mL of the standard or 0. 1 mL as needed.
- The amount of glucose needed (in mg) = Desired concentration in milligrams / decilitre x Volume in millilitres
- This is so because; 100 mg/dL multiplied by a volume of 100 mL equals 10,000 mg
Step 2: Conversion of given amount of glucose into moles
- Molecular weight of glucose (C6H12O6): A hanging of 180 has been installed to enable the proper housing of a hanging stem. 16 g/mol
- Moles of glucose = Total moles of glucose in mg /The atomic weight in g/mol
- Based on the above calculations from the regular packet, then the maximum of R can be obtained if ≤ 10,000 mg is consumed in a single sitting and if ≤ 180 g of food product is ingested at one sitting. 16 g/mol = 0. 0555 mol (approximately)
Step 3: Calculate the sum of glucose to be weighed
- Because you need to prepare a 100 mL standard, on that scale, you need to get the sum of glucose to be weighed in grams.
- Weight of glucose required (g) = x3 = 0. 0555 mol x 180. 16 g/mol = 10. 0068 g (approximately)
Step 4: Weigh and break up the glucose
- Weigh 10. On average, 0068 g of glucose is transferred into a 100 mL volumetric flask.
- Pour more refined water into the jar and stirring until the glucose fully dissolves.
- You should write on the carafe as Glucose Standard,100mg/dL or 5. 6 mmol/L.
