Phosphorus and Phosphate Detection Test Strips User Manual

Introduction

Thank you for purchasing the Phosphorus and Phosphate Detection Test Strips by Bartovation. These test strips are designed to detect orthophosphate ions and express the result as ppm phosphorus. To express the result as phosphate, multiply the result by 3. This user manual will guide you through the proper usage and troubleshooting tips for the test strips.

Instructions for Use

1. Dip the test strip into the solution to be tested for 1 second.
2. Remove the test strip and wait for 3 minutes.
3. Compare the color on the test strip against the color chart provided on the vial.

Troubleshooting Tips

• If the colors on the test strip do not match any color on the color chart, ensure that the test strip has been dipped for only 1 second and that you have waited for the full 3 minutes before comparing the colors.
• The pH of the sample should be in the range of 6-9. If the pH is outside of this range, it may affect the results.
• For best results, the temperature of the sample should be between 18-30°C (64-86°F). If the temperature is outside of this range, it may affect the results.
• Keep in mind that arsenate and silicates above 20 ppm will cause a false reaction, resulting in a yellow color. Fluoride, chlorides, and nitrites above 50 ppm will depress the phosphate reaction on the strips. Heavy metals and large quantities of oxidizing compounds may also depress the result.

Frequently Asked Questions

Q: Can these test strips detect triphosphates?

A: No, these test strips cannot detect triphosphates. Tripolyphosphates must be converted to orthophosphate first to be detected.

Q: Why are the colors on the test strip difficult to read?

A: Ensure that you have followed the instructions for use correctly, dipping the test strip for 1 second and waiting for 3 minutes before comparing the colors. If the colors are still difficult to read, it could be due to interferences such as arsenate, silicates, fluoride, chlorides, nitrites, heavy metals, or oxidizing compounds in the sample.

Q: How many test strips are included in the vial?

A: There are 50 test strips included in the vial.

Q: Can these test strips detect phosphorus levels below 5 ppm?

A: No, these test strips have a detection limit of 5 ppm phosphorus and cannot be used to detect anything below that.

Q: What is the shelf life of these test strips?

A: The shelf life of these test strips is not mentioned by the manufacturer. However, it is recommended to store the test strips in a cool, dry place away from direct sunlight to ensure their longevity.

Q: What does the Phosphate test strip detect?
A: The Phosphate test strip detects orthophosphate ions and expresses the result as ppm phosphorus. To express the result as phosphate, multiply the result by 3.

Q: Can this strip detect anything below 5PPM phosphorus?
A: No, this strip has a detection limit of 5PPM phosphorus, and can NOT be used to detect anything below that.

Q: Is any solution or field kit needed for testing with these strips?
A: No, no reagents or field kits are needed for tests, all you need is one strip and no chemicals.

Q: What is the color scale and marks on the test strip?
A: The test strip has a distinct color scale with marks at 0, 30, 75, 150, and 300 PPM phosphate (and 0, 10, 25, 50, and 100 PPM phosphorus).

Q: What is the shelf life of this product and how should it be stored?
A: The shelf life is approximately 18-24 months and the expiry date is printed on the product's label. To store this product keep it out of direct sunlight and at room temperature. Also make sure the cap is completely closed when it is not in use. The strips are packed in moisture-wicking opaque bottles to protect them from the elements and ensure their longevity.

Q: Can this product be used to test urine?
A: No, this product is not intended and will not work for testing urine.

Q: How do you compute readings in parts per billion (ppb) compared to parts per million (ppm)?
A: ppb is parts per billion, ppm is parts per million. 1000 ppb = 1 ppm.

Q: Are there any interferences to consider when using these strips?
A: Yes, arsenate and silicates above 20 ppm will cause a false reaction. Fluoride, chlorides, and nitrites above 50 ppm will depress the phosphate reaction on the strips. Heavy metals will depress the result. Large quantities of oxidizing compounds will also depress the result. Lastly, pH and temperature will affect the results. The pH of the sample should be in the range of 6-9. For temperature, the best results are obtained in the range of 18-30 C. Above or below this the reaction on the strip can be depressed.
