Pharmaceutical Analytical Chemistry Laboratory needed for conducting studies on the Active Pharmaceutical Ingredients APIs in an oil in water emulsion. We need to arrive at following conclusions by morphological/physical/chemical testing etc
1. Whether APIs are dispersed or solubilized (both APIs).
2. Phase in which each API is present (dispersed phase of emulsion or continuous phase of emulsion)
3. Particle size of API (for dispersed API). Separate PSD for each API if both are dispersed.
4. Globule size of emulsion.

LONG-TERM TESTING Cosmetics Laboratory needed for testing of multiple skin care projects in development. Quotes are needed on the following analytical services on finished released and excipient testing:
Release testing of Pramoxine Hydrochloride
Release testing of Hydrocortisone
Release testing of Zinc Oxide
Release testing of Titanium Dioxide
Release testing of Aluminum Sesquichlorohydrate
Finished good testing in a lotion and a spray
Finished good testing of in an ointment
Finished good testing of Zinc Oxide (17.0%) in a lotion
Finished good testing of Titanium Dioxide (2.3%) in a lotion
Finished good testing in a cream
Aside from release testing for the APIs listed above, do you routinely do release testing for cosmetic excipients, such as peptides, vitamins, humectants, etc...? I ask this question, because until we have a QC lab up and running, we will need to partner with outside labs to complete this testing. Would there be any savings if we were to submit multiple samples at once?

Test Request 17-01733
Analytical Chemistry Laboratory needed for chemical analysis of
1) Sodium Silicate
2) Fumaric acid
3) Tartaric Acid
4) Calcium hydroxide
5) Distillates (petroleum), solvent-dewaxed heavy paraffinic
8) Calcium Magnesium oxide
The analysis should identify and quantify the main ingredient and the main impurities (% w/w concentration of the sample) and should be followed by spectral data and detailed descriptions of the analytical methods.

Bioanalytical Laboratory needed grow Human Primary Trophoblast cells with serum and without serum for varying amounts of time (0, 24hrs, 48hrs, 72hrs, and 96hrs). Then immunofluorescence stain the cells with GLUT8 and Humanin for images.
We are looking to have a data point for every combination of serum, time,and staining:
serum: with and without
time(hrs): 0 (control), 24hrs, 48hrs, 72hrs, and 96hrs
staining: GLUT8 and Humanin (if possible, also co-staininng with lysosomal markers)
We also need to have a non-isotype IgG negative control.
For immunofluorescence images, we would like at least 40x magnification.

Plant based dietary supplement manufacturer need bioanalytical laboratory for blood testing for the measurement of NAD in human blood (Nicotinamide adenine dinucleotide - a coenzyme found in living cells). We are interested in proper quantitative measurement of NAD in blood, and from our research we came to know that HPLC is one of the methods to measure it.

Cosmetics analytical chemistry laboratory needed for investigation to identify and determine the cause of formulation incompatibility of finished product with a tendency to precipitate.In order to investigate where the formulation incompatibility is arising from it would assist to have an identification on the precipitate.I suspect that the precipitate is inorganic as it would not dissolve in Methanol, Propanol, Hexane and Chloroform.
LONG-TERM TESTING Analytical Chemistry Laboratory needed for accelerated aging study with testing monthly for a year.
Tests needed (per sample, per testing interval):
1. pH by electrode (single replicate)
2. Total active chlorine by electrode (duplicate)
3. Chloride ion by ion chromatography (duplicate)
Accelerated aging for two solutions: Unbufferrd HOCl solution, approx. 500 ppm and
#2. Buffered HOCl solution, approx. 500 ppm
50-60oC, dark (no pressure specified)
Once every 4 weeks for 1 year on a schedule I establish and send to you (based on when my client sends the samples)
My client will send 1 L of each solution, divided up into two 500 mL amber bottles (exact sizes still not provided). Both should be stored in the aging chambers, but only one should be sampled when performing tests (the other is back-up).
You will send the data to me and address questions/issues to me, but my client will be responsible for payment. IMPORTANT NOTE: Please send detailed quote with response.
